The 49-year-old actor, on his part, has never had any problem in doing a certain type of role as long as the story is entertaining.
"I think the fear of failure is what makes us stick to mediocrity. That's sad. Fortunately, I don't have a problem in doing any kind of films - be it serious one or a comedy. From a weird character like Babban in 'Ishqiya' or SSP Ajay Kumar from 'Seher' - it's quite varied.
"There are 'Golmaals' and 'Dhamaals' too. So, it doesn't matter to me. I just do a story if I feel, it will be fun to do and watch. I have never bothered about sticking to an image or breaking out of a mould."
On doing more or less the same character again, Warsi says, "I don't feel fatigued because our roles are really interesting. Had they been boring I would have been fed up. Here, there's no space to feel like that. This time too we have new jokes and skits."

The actor, who has become a pop culture reference point with his widely popular role of 'Circuit' from "Munnabhai" series, believes once a character becomes popular, directors should not make any significant changes in it.
Warsi harbours the ambition of becoming a director, but will not star in the film.
"I want to direct, 100 per cent. But I'm not getting any good producer. I have written two stories - one is action, the other is a love story. I'll start with either one. I won't feature in it."
The actor, who is known for his witty image on screen, says it would be difficult for him to write a script for a comedy.
"There's a difference between being witty and writing a comedy. A conversation is way different than penning a script for a film. I don't think I can do that (write a comedy). I can surely act in a comedy but I don't think like that.
