"I had not seen any film on such subject and I felt that I must make the film, so we made it in Marathi," Riteish said here in an interview.
"It is much easier to make such films in Marathi than Hindi because the Marathi audience accepts such unique subjects more as compared to the Hindi audience," he added.
"Yellow" is Riteish's second Marathi production venture, after hit film "Balak Palak".
"I think we were able to justify this (the subject of 'Yellow') more in Marathi," the actor said.
"If we have to remake it in Hindi, then we will have to work on it or do something else," he added.
"Yellow" features Gauri Gadgil, whom the film is based on, in the lead.
Riteish said: " 'Yellow' is an out and out emotional rollercoaster ride that will make you laugh. It's a sports film and also has an exciting climax."
Directed by Mahesh Limaye, "Yellow" also features Upendra Limaye, Aishwaraya Narkar, Usha Nadkarni and Mrunal Kulkarni.
