Megastar Amitabh Bachchan reportedly plays himself in Anurag Kashyap's short story in "Bombay Talkies".

A bouquet of four short stories, "Bombay Talkies" has contributions by four directors -- Kashyap, Karan Johar, Zoya Akhtar and Dibakar Banerjee. An ode to 100 years of cinema, the film is up for a May 3 release.

The 70-year-old plays a cameo in Kashyap's film and as part of the role, he will meet an ardent fan who comes to visit him from his home town Allahabad in Uttar Pradesh.

It is also said that Kashyap's short story will have a special song dedicated to the veteran actor. It will be released Sunday outside Big B's residence Prateeksha in Juhu, said a statement.

"Bachchan will play a cameo in the film. There is a surprise in store for him where a flash mob of 60 Bachchans (artistes dressed and masked like Bachchan) will launch the song in front of his home.

Big B has a tradition of having fans gathering outside his house on Sunday evenings in the hope of catching a glimpse of the veteran," said a source.
