Arshad Warsi, who received both critical and commercial acclaim for his comic roles in 'Munnabhai' series, is now

gearing up to play the serious role of a cop in his next film.

'Shaitan' is a crime thriller and I am playing a cop... It is a serious role,' the actor posted on his Twitter page.

Arshad tickled the funny bone of the audiences in 'Golmaal' too.
