Watch: Sidharth Malhotra displays his dark side in Ek Villain

Sidharth is seen as an innocent, harmless guy in love with a girl (Shraddha Kapoor) in the first half of the teaser trailer, before he transforms into a baddy. But is he the real villain?

The sweet Nikhil from Hasee Toh Phasee turns into a deadly villain in Mohit Suri's next Ek Villain.

All is well in Shraddha Kapoor and Sidharth Malhotra's life as they play lovers to the T. In what comes as a twist, Sidharth transforms into an out-and-out baddie.

"...It's a typical Mohit Suri kind of a film. Villain is different; it's an intense dark love story and there is a lot of action in it," said Sidharth in an earlier interview.

He further added that though there is a grey shade to his character, the film is a love story.

"Every one has a dark side in them and Mohit Suri has explored the dark side of me in this film. He is the best person to explore my grey shade. It's a grey shade in the film but it's essentially a love story," he added.

Sidharth will be seen in two distinct looks in Ek Villain.

Towards the end of the trailer, a voice calls out for someone saying, "Aye Villain", and Riteish Deshmukh turns. Is he the real villain?
