The trailer of the upcoming film Kolar Gold Fields (KGF) starring Sandalwood actor Yash was revealed in a glamorous ceremony in Bengaluru on Friday.

Filmed in retro style, the trailer begins with a scene depicting the birth of Yash's character Rocky in 1951 with the voice of Anant Nag narrating the events. It also shows glimpses of Rocky's childhood in Bombay before giving a glimpse of a battle in Kolar's gold mines. The dialogues in the trailer are in Hindi and Kannada.

KGF, which is set to be released on December 21, has one of the highest budgets for a Kannada film and has been directed by Prashanth Neel. It is a two-part period drama that traces the fortunes of a gangster over decades. 

The film is set in the 1970s with Yash playing the role of a gangster who leaves Mumbai for the infamous gold fields of Kolar. "Yash dons the role of an ambitious gangster and the film narrates his rise and fall. The first chapter will show how his childhood shapes him into the gangster he becomes," the film's director Prashanth Neel told the Times of India. 

Besides Yash, the film also stars debutant Srinidhi Shetty, Malavika Avinash, John Kokken and Achyuth Rao among others. Veteran actor Anant Nag will narrate the sequence of events in the film. 

The makers of the film unveiled its first look, a poster showing Yash holding an axe with a grim face, during Deepavali. They followed it up with a grand trailer launch in Bengaluru.
