Director Shriram Raghavan will start work on Gaurang Doshi’s film, ‘Happy Birthday’, in March. The film stars Amitabh Bachchan, John Abraham and Aishwarya Rai in a role that Preity Zinta turned down. This will be Doshi’s third venture featuring the Big B after ‘Aankhen’ and ‘Deewar’. Another heroine may join the cast to add a bit of glamour to the film. ‘Happy Birthday’ is being made on a bigger scale than his earlier films, and Doshi is expecting money to come in from corporates. We wish the team a very grand and successful ‘Happy Birthday’!!
