Mega hero Varun Tej said it's tough to do comedy. "I have always looked up to Peddananna (Chiranjeevi) and Babai (Pawan Kalyan) for their comic timing and mannerisms. I make sure that I don't imitate them on screen," said Varun. About his latest movie 'Mister' Varun said, "The film has an honest script and it fulfills my desire to do a proper love story." 'Mister' is directed by Sreenu Vaitla and is releasing on April 14th.
