Recently, director, and now actor, Sudhir Mishra -- who made the critically acclaimed Hazaron Khwaishen Aisi and Is Raat Ki Subah Nahin -- finally got his revenge against telemarketers, who keep harassing him to take a loan or credit card.

He got a chance to vent his anger in Madhur Bhandarkar's upcoming film Traffic Signal -- his maiden appearance as an actor.

There is a sequence in the film in which temperamental don, played by Sudhir, gets a bashing from his bosses. At around the same time a few telemarketers call him. Irked by the calls, he tells them to meet him, and then beats them them up.

This is just one of the many scenes punctuating this dark film.

"When I called up Sudhir for the role he laughed it off saying he could not act," Bhandarkar said. "But I wanted a certain look that Sudhir has. His intense-brooding eyes and the tall stature fit well for the character of Bhaijaan. So I persisted and he agreed. We have given him a plain white pathanis and kajal-in-the-eyes look."

Shot in the streets of Mumbai, the film boasts an interesting star cast: Konkana Sen Sharma, Ranvir Shorey, Neetu Chandra (who also starred in Priyadarshan's Garam Masala) and Kunal Khemu.

The film promo begins with loud honks, sari-clad eunuchs, persistent gajra-sellers, ever-busy dabbawallas, cranky taxi drivers, spaced out druggies to showcase life around a traffic signal. Sudhir is the don who rules their lives.
