His turn as the funny goon, Circuit, in Rajkumar Hirani`s `Munnabhai` series made him a household name but Arshad Warsi says that he is tired of doing comedy and is scouting for serious roles now.

The actor is gearing up to don the black kurta and gold chains once again for the third installment of the series but rues that his immense popularity as Circuit means that most of the producers want to bank on the image.

"I am tired of bad comedy. I am fed up of it because I have done too much of them. I need a break. I want to do something different and serious. Something that I did in `Seher`," Arshad told.

"`Munnabhai...` is likely to go on floors in September. I will start working on it soon. Honestly speaking I love the character of Circuit. But playing him once again is quite scary for me. People have huge expectations and it is a big challenge to live up to it," he said.

With `Ishqiya` where Arshad pleased the critics and `Golmaal 3` which was a box office success, the actor has had a good year in 2010.
