The film had two endings; the makers felt the Indian audience will not fathom Amitabh Bachchan's character not getting justice. Hence the ending for the Indian audience had Amitabh repenting and being locked away by the police, the moralistic ending. The overseas ending shows Amitabh bribing the police and on the loose chasing Akshay Kumar and Arjun Rampal.
The original title of the movie was "All The Best", but while in production, the filmmakers decided to change it to a Hindi title, believing that an English title wouldn't be so appealing to the Indian audience.
Bipasha Basu had a larger role, but her scenes were edited out, leaving her with just a special appearance in one of the songs.
Akshay Kumar, too, fell out with Gaurang Doshi, the Producer, by the end of this movie. Due to the fallout, getting the oft-discussed sequel off the ground has been a tough proposition for the makers.
After an unpleasant working relation with the Producer during the making of this film, Vipul Shah decided to turn producer himself and went on to direct and produce Waqt with Akshay Kumar and Amitabh Bachchan.
