It might not instantly spring to mind as the biggest budget-busting film ever, but 2007's Pirates of the Caribbean: At World's End takes the prize.
Johnny Depp's swashbuckling adventure epic, the third in the franchise, cost $US341.8 million ($A369.81 million) to produce, in a list compiled by Business Insider, which takes in reported or estimated budgets and inflation.
But it more than provided bang for the buck, by pulling in $US963 million ($1.04 billion) at the worldwide box office.
The film, directed by Gore Verbiniski, reunited Depp with Geoffrey Rush, Orlando Bloom and Keira Knightley, and scored Oscar nominations for make-up and visual effects.
Elizabeth Taylor's Cleopatra comes in at number two with a modern-day budget of $US339.5 million.
Titanic takes the third spot with $US294.3 million
With a surprisingly low turn-out on the list for comic-book franchises, only Spider-Man 3 makes it onto the list with $US293.9 million.
