Fox Star Studios acquired rights for the Indian adaptation in 2014, after which it underwent series of casting and screenplay changes for four years. Filming commenced under the title Kizie Aur Manny by late June 2018. The film was shot across Jamshedpur and Ranchi with sporadic schedules in Mumbai; apart from the last one in Paris, France. The score and soundtrack were composed by A. R. Rahman, with lyrics by Amitabh Bhattacharya. The cinematography and editing were performed by Setu and Aarif Sheikh, respectively.
The theatrical release of the film suffered due to delays in post-production and because of the COVID-19 pandemic. Adding to these reasons was Rajput's death on 14 June 2020, which resulted in the film being released digitally on the Disney+ Hotstar streaming service on 24 July 2020. In honour of Rajput, the film was made accessible without subscription in India and selective countries on the platform. The film received generally positive reviews from critics who praised the running time, the performances of Rajput and Sanghi, story, characterisations, soundtrack, cohesion, screenplay but criticised the lack of emotional depth and direction.
21 year-old Kizie Basu is fighting thyroid cancer when she meets twenty-three year-old Immanuel "Manny" Rajkumar Junior, who has previously suffered from osteosarcoma and is in remission. Manny and his friend Jagdish "JP" Pandey, who is suffering from glaucoma and is blind in one eye, are making a film together in which Manny plays the male lead, inspired by well-known actor Rajinikanth. Manny invites Kizie to be the female lead. The two bond over his love for Rajnikanth's films and her love for Hindi music, specifically an incomplete song by retired songwriter Abhimanyu Veer. Kizie and Manny gradually fall in love as they shoot scenes for Manny and JP's film. They decide to make 'Seri', the Tamil word for 'Okay', their secret word that will help them remember that everything will be okay in life and that it is important to stay positive. After an operation, JP loses sight in his second eye, making him go blind.
One day, Manny informs Kizie that he has managed to track down Abhimanyu and get in touch with him. Kizie e-mails Abhimanyu, who replies that he'll answer all her questions if she's able to visit him in Paris, where he lives. Kizie and Manny convince Kizie's parents to allow them to take the trip and manage to convince them, on the condition that Kizie's mother joins them. As they are making arrangements for the trip, Kizie's cancer worsens and she is suddenly hospitalised.
After her recovery, she is weakened and initially distances herself from Manny, but they eventually reconnect. They go to Paris to visit Abhimanyu, who turns out to have no conclusive answers and no reason for not finishing the song, disappointing Kizie. Soon after, Manny informs Kizie that his cancer has returned and that he is now terminal.
As Manny's health deteriorates, Kizie convinces him and JP to finish the film. Manny then invites JP and Kizie to his mock funeral, where they deliver eulogies that they have both prepared. Manny dies a couple of days later, leaving a letter for Kizie, explaining that he had finished Abhimanyu's song for her and had even convinced Abhimanyu to help him with the music despite considering him a terrible person.
JP's finished film premieres in an open-air theatre to a heartwarming response from the crowd, which consists of Kizie and Manny's friends and family. In the final scene of his film, Manny breaks the fourth wall and directly speaks to Kizie, telling her to live life to the fullest, to which she replies "Seri".
In August 2014, Fox Star Studios confirmed adapting The Fault in Our Stars for Bollywood. In an interview with Bollywood Hungama, Fox Star Studios CEO Vijay Singh stated "The Fault in Our Stars defines and resonates with the emotions of today's youth, across demographics". In September 2014, Varun Dhawan and Deepika Padukone were reported as the lead pair for planned remake. Producer-director duo Homi Adajania and Dinesh Vijan confirmed their association with the film. In an interview with aforementioned, the latter stated: "It's a story that I really feel needs to be told here. For me it's poignant at a time when we are consumed by technology and are manically running this make-believe race we think is "Life". Also, Karan Johar initially held the rights to remake the film. By October 2015, the duo backed out citing creative differences and Mohit Suri being brought on board as director. Dhawan could not be onboarded citing schedule conflicts. In an interview with Hindustan Times, Rajput denied being approached for the remake. He later confirmed through his Twitter handle about the film. In late 2016, the film was considered for debutante female lead for Sara Ali Khan, who backed out and her mother confirmed the project to be shelved. By December 2016, Alia Bhatt and Aditya Roy Kapur were considered for the project.
In June 2017, reports stated that Ishaan Khatter and Janhvi Kapoor both as debutantes were supposed to star in the remake. The project was then to be directed by Shashank Khaitan, who eventually wrote the dialogues for the film and went on to direct them instead in Johar's remake of Sairat, titled Dhadak. The screen test was completed by 25–26 June 2017. Also, the project was considered under Johar, reportedly, with Kapur being dropped off. However, the news media incorrectly cited the debutante pair as leads in the remake.
In August 2014, India's Fox Star Studios announced it would adapt the novel into an Indian Hindi-language film, with the working title of Kizie Aur Manny. Johar was supposed to produce the film but eventually backed out.
In October 2017, the project was confirmed to be starring Rajput as the male lead. Chhabra was selected to direct the film and was in stages of scripting with Khaitan and Suprotim Sengupta. Reports confirmed that Johar was not a part of the project. In March 2018, Chhabra confirmed Sanghi as the female lead opposite Rajput. Whilst Chhabra served as casting director for 2011 film Rockstar, he recalled Sanghi's association with him. She was looking for a few ad jobs, was mature young lady by 2020. Since Rockstar, he wanted to make a film with her one-day, noting the film script as "ready to fit her in". That very month, A. R. Rahman was reported to compose the film's background score and soundtrack album. Mukherjee, who had previously worked with Rajput in Detective Byomkesh Bakshy!, confirmed her presence in the project by September 2018.
Screen tests were completed by end of June 2018. In an interview with IANS, Rajput stated: "I and Mukesh share a great bond. He gave me my first film and I promised him that I would definitely be in his. This was the first film I signed without reading the script, as I know Mukesh is a terrific director. And now that I have read the script, I am glad that I said yes." In an interview with Mid-Day, Chhabra stated he was able to visualise things as a whole with "Kizzie Aur Manny". He gave the film his own language without getting influenced by the casting, thereby a fresh touch to the love story. At the 2018 Jio MAMI Mumbai Festival, Former UTV studio head Rucha Pathak, Chief Creative Officer of Fox Star Studios, India stated that it took four years to write the script of 'Kizie Aur Manny', as the "Word to Screen Market" is really bringing the world of cinema and literature together. She confirmed Sengupta for the film's screenplay and Khaitan for the dialogues.
On 8 February 2019, the film's title was changed officially to Dil Bechara. Pathak added that the change was to embody the theme emerging out of the title track composed by Rahman and lyricist Amitabh Bhattacharya.
In an interview with Gayle Sequeira at Film Companion, Sanghi summed up her character role "Kizie" in two phrases: "Emotionally demanding" and "oscillating between extremely happy to extremely romantic to extremely tragic". Kizie played the role of a Bengali girl where Chhabra wanted her to reach a state where she could converse in fluently in Bangla with Swastika Mukherjee (Kizie's mother) and Saswata Chatterjee (Kizie's father). For Sanghi, it took months of diction and cultural training, which she completed with the help of an NSD graduate. Sanghi also joined cancer support groups and spoke to many young survivors to understand the psychological and emotional impact that an illness can have on those who get diagnosed. In addition to Sanghi, Sahil Vaid in his role as "JP" also spent time with such patients. He called his character role both chirpy and cathartic. For the role of Kizie's mother, Mukherjee stated: "I think my natural maternal instincts kicked in for this... I didn’t really need to work very hard." She found resemblance with her real life motherly behaviours into this role, extending the 'dormant mother-in-waiting went into full-on active mode'. In this interview with The Telegraph she went on to add that Kizie's father's role, played by Kahaani and Disney's Jagga Jasoos fame Saswata Chatterjee, was shorter than her role and people could connect with Dil Bechara on a personal level because it portrayed household scenes grounded with Indian cutures.
Principal photography commenced in Mumbai on 29 June 2018, where Rajput shared a promotional still titled "New Beginnings" from the sets on Twitter. Filming began in Jamshedpur on 9 July 2018. The film poster with its former title "Kizie Aur Manny" was released on the same day. Post his recce, Chhabra mentioned, "I needed a place with a small town vibe and had heard a lot about Jamshedpur. I knew instantly that this was where I wanted my love story to take root."
In mid-October 2018, Chhabra was suspended of services by Fox Star Studios, on account of allegations for sexual harassment amidst #MeToo movement in India. This resulted in filming stalled until late December 2018. A 9-day filming schedule planned, in Paris was deferred owing to the civil unrest across France and dates availed for filming scenes with Saif Ali Khan lapsed.

They share stories of how cancer has affected their lives, and soon blossoms a beautiful friendship." Critic based at Inquiry, Musanna Ahmed called it a "pretty nice story" adding on : "...much of your enjoyment will depend on if you cared for John Green’s story the first time [...] It is for those who haven’t read the book or seen the original film because this takes plays almost beat-for-beat the same." In her review for The National, Aarti Jhurani praised the film length, calling it a sweet story is worth a watch for the myriad characters" She awarded a 4.5 score on a scale of 5, noting Sanghi's effortless portrayal of Kizie and Sushant Singh Rajput's bowing out with a bang.

Dyuti Gupta of SheThePeople.TV wrote: " Sushant’s final film Is a poignant tribute to his life and talent".
On the contrary, Rachit Raj of Medium presented a mixed view: "A decent love-story that tries too much to reinvent itself." Hannah Abraham of Cultured Vultures summarised: "While transposing the idea for Indian audiences, much of the subtlety, nuance and emotional depth of the original film seems to have seeped through the cracks." She assigned the film a score of 6.5 on 10, calling it an average watch and certainly not comparable to the original. Gautaman Bhaskaran for Arab News wrote: "Dil Bechara is not a great work. It is casually written and poorly directed."

Assigning 3.5 stars (out of 5), he noted the film direction to pick shades of Rajesh Khanna's 1971 film Anand. Saibal Chatterjee for NDTV wrote: "The film will obviously always belong to Sushant Singh Rajput – on the money all the way, his performance demonstrates exactly why the chops he possessed weren't ordinary." He scored the film 3 out of 5.Taran Adarsh gave it four stars out of five. He described the film as a "beautiful love story. Sushant Singh Rajput is top notch, charismatic in light moments, makes you moist-eyed in emotional parts. Sanjana Sanghi is wonderful."Komal Nahta of Film Information called "It dull and depressing." Sreeparna Sengupta of The Times of India gave the film 3.5 stars (out of 5). She praised: "Given its poignant premise, ‘Dil Bechara’ makes for a very emotional watch.

At Scroll Magazine, Udita Jhunjhunwala reviewed in positive: "Sushant Singh Rajput’s final film is a moving experience." In his review for The Hindu, Kennith Rozario said the film was a surreal experience that bridges reality and fiction although quite shallow in its storytelling.
Also, Stutee Ghosh of The Quint pointed "This one is 1 hour and 40 minutes and the rush to get to the denouement robs the film of its magic making it an average affair which is a pity." She gave the film 2.5 stars (out of 5). Critic Baradwaj Rangan, whose review was published in Film Companion, titled: "A Watchable-Enough Romance That Offers A Small Sense Of Closure To A Big Tragedy" He stated: "The weakest parts are the film’s stabs at comedy and its attachment to that musician who’s become a JD Salinger-esque enigma." Reviewing at the OTT platform Arre, Poulumi Das stated: "Dil Bechara is not the most complicated or ambitious film but it does meet its own expectations. It is by no means a perfect film but it is not one without feeling" Critic and author Anna M. M. Vetticad stated: "Dil Bechara subtracts from the positives of the original with its slipshod rewriting, sloppy editing, and ordinary production quality."

Critic Shubhra Gupta for The Indian Express acknowledged the film as "equal parts dirge and catharsis", assigning it 2.5 starts (out of 5). She noted: "It is the occasional sweetness that Sushant Singh Rajput and Sanjana Sanghi manage to rustle up that carries the film." Critic Komal Nahta stated "Dil Bechara is a dull fare. In normal circumstances, the film would have not been able to do well in the cinemas".
