Production
In early May 2017, G. V. Prakash Kumar signed on to appear in the Tamil remake of the Telugu film 100% Love, with the film's original director Sukumar turning producer for the Tamil version. Directed by Chandramouli, the film was revealed to have cinematography by Dudley and music composed by Prakash Kumar himself. For the leading female role of an undergraduate student, the team held discussion with Hindi actress Shraddha Kapoor, but she was not interested in working on the film. The team then considered and approached Tamannaah Bhatia to reprise her leading role from the original film, though she declined the offer. Likewise, Sayyeshaa Saigal also turned down the offer. In early June 2017, the team held discussions with Lavanya Tripathi for the lead role, before finalising Hebah Patel for the role. In a turn of events, Hebah was replaced by Lavanya in late June 2017 as she became available and the makers found her most suitable for "to pull off the look of an undergraduate student". In addition to the two lead actors, the cast finalised also included Nassar, Livingston, Ambika and comedians Yogi Babu and Sathish. It was revealed that the film would mostly be shot in London and about ten percent of the film will be shot in India, with production beginning in August 2017 under the title of 100% Kadhal.

The start of the film's first schedule was delayed from August to September 2017 as a result of Lavanya's commitment to a Telugu film directed by Parasuram starring Vijay Devarakonda. Chandramouli had intervened and requested the makers of that film to allow Lavanya to work on 100% Kadhal, following which Lavanya was dropped from the Telugu film despite having shot for several weeks. Unhappy with Chandramouli's interference, Lavanya withdrew from 100% Kadhal in mid-September and was replaced by Shalini Pandey, who had previously appeared in the Telugu film Arjun Reddy (2017).

After a promotional shoot held in September 2017, the film began production in Chennai during mid-October 2017. In a turn of events, cinematographer Dudley was replaced by Ganesh Rajavelu, while Mu. Kasi Viswanathan and Thota Tharani handled the editing and art direction respectively. The film completed its shoot in August 2018, and thereafter began post-production work.
