Despite its initial difficulties, 'The Dark Knight' has reigned supreme at the US box-office since its release three weeks ago.
Last week it saw off the hopes of 'Total Recall', with the remake of the 1990 sci-fi disappointing at the box-office.
Yet despite taking over $328m, this could be the weekend when Batman finally meets his match, and he's called Bourne, or rather Aaron Cross, the character who replaced Jason Bourne in the latest installment in the 'Bourne' franchise, played by Jeremy Renner.
According to MTV, box-office analyst Jeff Bock said: "Even without Matt Damon, 'Bourne Legacy' will definitely knock the Batman out of the box-office belfry and probably get close to $45 to $50 million."
Yet it's not all bad news for Bruce Wayne and chums, as the film is still set to see off the challenge of Will Ferrell's political comedy 'The Campaign'.
Bock said: "Political comedies, even starring these two comedy heavyweights, don't usually get elected to the top of the box office."
As for 'Total Recall'? The movie is in real trouble as it's up against two heavyweight franchises, possibly rivalling this summer's 'Battleship' as this summer's major flop according to Bock.
