Amitabh Bachchan, Arjun Rampal in Kushan Nandy's Thriller

Amitabh Bachchan and Arjun Rampal will team up for Pritish Nandy's son Kushan Nandy's yet to be titled thriller, a source close to Nandys tells exclusively.

The female lead is yet to be finalized.

Kushan is still working on the film's plot, but filming is scheduled to begin in the last quarter of 2011.

In the summer of 2009 Bachchan had blogged that he and Kangana Ranaut will star in Pritish Nandy's thriller, The Actor, which will be directed by Pritish's son Kushan.

"The film was based on Bollywood film industry. But after a lot of structural changes they finally shelved the film. Now this script came along and Big B gave his nod," our source tells us.

Amitabh and Arjun have teamed up several times in the past: Aankhen (2002), Ek Ajnabee (2005), Darna Zaroori Hai (2006), Kabhi Alvida Naa Kehna (2006) and The Last Lear (2008).
