Vivek Oberoi has been preparing for his next film Zilla Ghaziabad.

The actor has begun doing research on Satbir Gujjar, the character he portrays in the movie.

Satbir was a Ghaziabad-based outlaw. VO will be sporting a moustache with a stubble and short hair getting as close to the look of Satbir.

The film is based on northern gang wars that took place in the '80s and '90s.
