India, Sept. 22 -- The trailer for Sujeeth's much-awaited gangster film, They Call Him OG, aka OG, was launched after much delay on Monday afternoon. Starring Pawan Kalyan, Emraan Hashmi and Priyanka Mohan in lead roles, the film tells the story of a gangster called Ojas Gambheera and is set in Mumbai.

The trailer begins by telling the audience that gang wars have begun in Mumbai again, but this time around, the target is someone called Satya Dada. Emraan's character, Omi Bhau, seems to be the one hunting him, and someone remarks that there's only one person who can stand against him. Pawan's Ojas Gambheera, who is now living an idyllic life with his family, comes out of retirement to set things right.

OG is directed by Sujeeth and prod...
