The seed that gave rise to Thithi was planted during a visit that Reddy made to Nodekoppalu village in the Mandya district of Karnataka, the home town of the film's co-writer Eregowda. Reddy found the village, seen through the eyes of an insider, to contain within itself a highly cinematic world. Reddy then did a year-long stint at
Prague Film School. Upon returning, he re-visited the area frequently, conducting a three-month exploratory process to better acquaint himself with the world. During this process, Eregowda and Reddy met and decided to revolve the film around three protagonists, Channegowda (Gaddappa), Thammegowda S. (Thammanna), and Abhishek H.N. (Abhi), even before the idea for the story of the film had taken shape. Keeping the true life personalities of these three leads in mind, Reddy and Eregowda then began developing a screenplay that revolved around the death and thithi of a 101-year old cantankerous centenarian, Century Gowda. After Reddy and Eregowda finished the script, they had an ambitious 160 page screenplay with over a hundred characters. They then moved into pre-production work which included an eight-month long casting process to find actors to fill out smaller roles and putting together a crew for the film. At this stage, DoP Doron Tempert, Reddy's batchmate from Prague Film School, joined the development process and started building the story-telling style and approach with Reddy. Production started in
Nodekoppalu in January 2014. The film was shot in multiple schedules split over a period of five months, the longevity of the shoot owing to the logistical challenges of working with non-actors. When the film was in the rough cut stage, the film made it into
NFDC's Film Bazaar where it was adjudged as the Best Work In Progress fiction feature and awarded a free
digital intermediate at Prasad Labs, Mumbai. The film, still a work-in-progress, premiered at the Locarno Film Festival in August, and then went on to have its Indian Premiere at the
Mumbai Film Festival. The film was finally completed in December 2015. ==Reception==
