"I'm playing a Casanova in the movie and Punit is my source of inspiration. He used to come shirtless, get a massage done on the sets, joked around with the crew and lots more," Imran said during an interaction on TV show "Star Verdict".
"I did exactly what he does always. In fact, it seemed like I was living his life," he added.
In the film, which releases Nov 22, Imran essays a south Indian boy named Sriram. Actress Kareena Kapoor, who will be seen as a social worker Dia, will be seen as his love interest. The movie also features Shraddha Kapoor in a guest appearance.
