"This film is based in the 1960s and I love the way Pran-ji used to act. So I have tried to do what he did," he said.
Honey Singh says acting is the toughest of all performing arts.
"I think acting is the most difficult one among all the performing arts. Writing songs, making music and singing is important to me and I do all three," he said.
He wanted to have a brush with acting.
"You play someone you are not...So I wanted to learn it. Anant Mahadevan is a senior actor and filmmaker and Himesh (Reshammiya) asked me if I would do a small role and I said yes," Honey Singh said.
`The Xpose` stars composer-actor Himesh Reshammiya in the lead. It is a detective thriller, and besides some new faces, the film also stars Irrfan Khan.
The movie will hit theatres May 23.
