Mumbai, March 22 -- Currently, Aditya Roy Kapur has four films in the pipeline. The actor, who has mainly played an urban guy in love stories, will be seen in a diferent avatar for his upcoming roles. So much so that the actor is not restricting himself and is even open to playing an out-an-out negative character if an opportunity comes his way. "When you say negative, that sounds like it will be really fun. As an actor, it gives you a lot of freedom. I'd enjoy that," says Aditya. Talking about a negative character that he considers to be one of the most unparalleled villains on screen, he says Joker was an exceptional role for the late Heath Ledger, and the success it brought to his career. "The Dark Knight (2008) is a film which I have watched a lot of times, and everyone knows Joker is a great villain. But when I recently watched the film again, I was blown away by what Heath Ledger did. I don't think that happens with every actor. There are some roles that just connect with you more than others. They connect with you on a deeper level. I feel, Joker was one such role for Heath Ledger," says Aditya....
