The film is one of the biggest Hindi cinema box-office flops of all time.
To prepare for his role, Abhishek Bachchan trained in sword-fighting under veteran fight director Sham Kaushal.
According to Abhishek Bachchan, the persona of Drona is based upon superheroes without super-abilities, like Zorro, the Phantom and Batman.
Shiney Ahuja was approached for Kay Kay Menon's role but rejected it.
Action coordinator Sham Kaushal studied traditional Indian martial arts like Gatka (adapted by the Sikhs), Kalaripayat (developed by the Malayalams) and Chhau (originating in West Bengal) for incorporation into the film's skirmishes.
