'The Dark Knight', starring Christian Bale and the late Australian actor Heath Ledger, has crossed the $500 million mark in just six weeks.

The movie's accomplishment is even more impressive considering that it grossed half billion in just half the time it took the mega-hit 'Titanic', reports thesun.co.uk.

The 'Batman' sequel is only the second film in history after James Cameron's 'Titanic' to top the half-billion-dollar mark. The Leonardo Dicaprio starrer made $601 million. Reports suggest 'The Dark Knight' could still earn more than 50 million pounds (nearly $90 million).

Commenting upon the film's record breaking profits, Bale said: 'It's wonderful! But I'm not a business man. I just enjoy doing what I do and whatever happens after that is gravy.'
