He might be the superstar of Bollywood today, but the actor started off with negative roles, and how! Shah Rukh Khan's pitch-perfect acting as the villain not only earned him brownie points, but also fetched him interesting roles thereafter. As he gears up for his dual role in Fan, we take a look at the five reel instances where he took obsession to another level…read on:

Fan (obsessed with a star):

Perhaps the most-awaited film of the year stars SRK in a dual role of superstar Aryan and Gaurav, a ‘fan’atic. How the two face-off and what happens when tables turn…these are the things we are waiting to see, no? *so excited!*

Darr (obsessed stalker):

In this Yash Chopra thriller, SRK played an obsessed stalker who could go to any length to get K…K…K…Kiran. With blood-stained walls, crazy stalker tendencies and generally making Kiran’s life hell was the plot of the super hit flick. Needless to say, King Khan aced it with his striking acting skills.

 Baazigar (obsessed with revenge):

In another outing as the bad guy, SRK took his revenge scene to crazy levels. He not only knocked off Shilpa Shetty’s character by pretending to love her, but also ruined Kajol’s character despite actually loving her. Phew! Foot-tapping music and an engaging plot made the movie a bumper hit.

Don (obsessed with winning):

His arrogance and pride made Don the most wanted criminal. But his obsession with winning eventually became his downfall. Also, the various twists and turns offered us a glimpse of the actor’s versatility.

Anjaam (obsessed with an air hostess):

When he fails to land his obsession aka Shivani (Madhuri Dixit), he vows to make her his own. He kills her husband, mows down her sister and daughter, and ultimately succumbs to his maniac love. Both SRK and Madhuri compete with each other to deliver a memorable performance.
