Actress Deepika Padukone says when it comes to acting, she is selfish."We all work so hard on every movie and want each one to have its own space to do it... sort of properly. But I look at the overall picture, of course I am selfish as an actor," Deepika said at the unveiling of the video of "Wat wat wat" song from her forthcoming film "Tamasha".Deepika is elated that this year has been one of the best. "While 39Piku39 has already released, now we have 39Tamasha39 and then 39Bajirao Mastani39. So, as an actor I am very happy," said the 29-year-old.Talking about "Tamasha", she said: "39Tamasha39 is something that talks about breaking stereotype and expressing things differently. And I think we were expressing the character39s mood differently, how one could normally express that."The movie also stars Ranbir Kapoor.
