Varun Dhawan and Boman Irani who will be seen sharing screen space in Rohit Shetty's 'Dilwale' actually go back much longer than their new equation as co-stars. Boman's son Kayoze was Varun's co-actor in his debut film 'Student of The Year', in which Boman had even made a guest appearance. And from having being called as 'Uncle' or 'Sir' by Varun for the past few years now, it was a feat of sorts for Boman to ease Varun into treating his friends dad as a colleague.

"I've known Varun as a son's friend and he has always been very respectful towards me as Kayoze's dad. But as co-actors, I consciously wanted to blur the lines and get him to feeling comfortable around me as a friend and a co-actor and not as an ‘uncle’. Of course, Varun still shows me the kind of respect he always has but it’s a more relaxed equation we now share," says Boman.

The actor elaborates, "I really think that while it's good to be serious about our work, it's not such a good idea to be so serious about ourselves. I wanted Varun to enjoy the process and not inhibit the performance because of me being 'sir' for him. So, not just Varun, I feel that it's important to make your co-actors feel comfortable and get into the space of friends. It really helps."

Well, so that's the secret of Boman getting along with all his co-actors then!
