"I had never thought of doing a movie. My aim was only to do stand-up comedy and I was doing it well," said Kapil.
Anukalp, the writer of his show, has also written Kapil's debut movie "Kis Kisko Pyaar Karu".
"He (Anukalp) had shown the script to Abbas-Mustan some time back and the belief Abbas-Mustan showed on casting me inspired me to do the movie," Kapil said.
Kapil was too busy shooting for "Comedy Nights" when he signed the movie.
"I gave the mahurat shot for the movie after a night-long shoot of 'Comedy Nights'. I didn't slep all night, but I don't know how I got the energy," he said.
Kapil, who made his entry in the entertainment industry through a comedy show, has been here for over eight years.
"TV has given me everything. There was news that I had said that I hate how TV works. But the fact is that I had a slipped disc in February, and in TV, you have no option but to work.
"I had to produce the episode for the next telecast. This is the thing about TV that I don't like. I pulled off till June, spoke to my doctors and then decided to quit as I could not pull it further," he said.
There were rumours that his popular TV show stopped as he had to go to US.
"People feel I stopped the show for shows in the US but that's not true. The commitments were quite prior to all this. People had invested there as well, arenas were booked, tickets sold, so I had to do it."
"But I will continue TV as it has given me a lot," he added.
"Kis Kisko Pyaar Karu" also stars Arbaaz Khan, Manjari Phadnis, Amrita Puri, Simran Kaur Mundi, Elli Avram, Varun Sharma, Supriya Pathak and Johnny Lever's daughter Jamie Lever. Directed by Abbas Mustan, the movie is set to release on September 25.
