Playing villain one of the greatest highs: SRK

Now-a-days negative rule has become very popular  like 'Baazigar', 'Darr' and 'Anjaam' and now Farhan Akhtar's 'Don 2: the King is Back'.
It started with Abbas-Mustan thriller 'Baazigar' in which SRK played a negative role. Yash Chopra's 'Darr' (1993),  was the story of an obsessive lover played by Shah Rukh. A same story in 'Anjaam' had the actor play a bad guy opposite Madhuri Dixit in the female lead.

Ask him if the negative characters are liked and memorable, Shahrukh says, "Evil or devil, black or little grey characters, be it in books, stories, films or television, have some sort of an attraction. I started with theatre and there was nothing like a heroic character. There was a central character or an important character. I have played good and bad on stage. When I joined films I got a chance to play these characters again."
"Now, after 15-20 years, I got a chance to play a negative character in 'Don'. There is a justification for the character to be negative, to be bad. I enjoy doing it. I am in no way glorifying negative characters. These are stories and characters. But as an actor, it is one of the greatest highs to play a villain," he said.
