 Madhavan shot for the film simultaneously in late 2006 alongside Mani Ratnam's "Guru" (2007), and expressed his joy at working alongside Ghosh and Bachchan for the first time.The entire team charged little fees for the project, with Konkana rejecting the opportunity to have a vanity van on the sets.The film's shoot was delayed for a month due to Bachchan's illness, though scenes for both versions were subsequently shot rapidly in Calcutta in October 2006.
