Genelia apparently realised on reading the script of the film that the role offered to her was just an ordinary one. Moreover, history tells that Rohit Shetty's films are mostly male-centric. So, she decided to opt out of the film though it features big actors like Abhishek and Ajay.
However, sources close to the actress have a different story to tell. They said that she couldn't do Bol Bachchan, as her dates clashed with Navdeep Singh"s film, where she acts with Abhay Deol.
Actress Genelia D"Souza was supposed to act with Abhishek Bachchan and Ajay Devgn in Bol Bachchan but she opted out, as she thinks she has nothing much to do in the film. Sources said that director Rohit Shetty is now trying to find a replacement.
