Ajay Devgn returns to action roles

The trailers of the movie has already been released in theatres with Kites last week.

Milan Luthria, the film's director says that the movie is seen through the eyes of a police officer and traces the changing face of the Mumbai underworld.

The film, set primarily in 1970 Mumbai, follows the rise of Sultan (Ajay Devgn), and his eventual fall, when his protege Shoaib (Emraan Hashmi), challenges his supremacy, and usurps power to rule the murky underbelly of Mumbai, Luthria said.

Ajay last played an underworld don in Ram Gopa Varma's Company in 2002.

After the success of its previous release, LSD - Love Sex aur Dhokha, Balaji Telefilms' latest project, Once Upon Time in Mumbaai, is directed by Milan Luthria and stars Ajay Devgn, Emraan Hashmi, Kangana Ranaut and Prachi Desai.

Once Upon a Time in Mumbaai is all set to release worldwide on July 30 (2010).
