Karan Johar had earlier done small roles in films like Dilwale Dulhaniya Le Jayenge,Salaam -e-Ishq,Luck By Chance to name a few.

However this time Karan would be essaying a full-fledged character. He will be playing a rich businessman with shades of grey,who will be a crucial factor in the life of Ranbir Kapoor’s on-screen character.

Karan Johar has reportedly charged a mere Rs 11 from his Bombay Talkies co-director.

Meanwhile the film fraternity is sending Karan ‘tweets’ of encouragement.

D-Day director Nikhil Advani said: @karanjohar Break a leg!!! Try not to overshadow young Mr. Kapoor.

Actor Tusshar Kapoor also tweeted: @karanjohar All the best,still remember my 1st day,but your an expert at facing the camera!

The film also features Anushka Sharma in the lead role.

Ranbir and Anushka will play lovers whose lives intermingle with the evolution of the city of Bombay,through the 50s to early 70s.

The first film of a trilogy,as planned by Anurag Kashyap will release worldwide on December 2014.
