Saif Ali Khan has played a man with negative shades before in Kya Kehna and Ek Hasina Thi.

But it is Vishal Bharadwaj's Omkara [Images] that is rumoured to host his best villain act yet.

Saif plays the crafty Langda, whose pride is hurt when chieftain Omkara (Ajay Devgan [Images]) appoints Kesu (Vivek Oberoi [Images]) as his chief lieutenant. He hatches a plot to falsely implicate Omkara's lover Dolly (Kareena Kapoor [Images]), in a love affair with Kesu.
