Three most expensive movies ever made

Taking into account the way production costs are disclosed, three most expensive movies to produce were:

Rank	Title	Year	Adjusted film costs in millions (est.)	Nominal film costs in millions (est.)
1	Cleopatra	1963	$320m	$44m
2	Pirates of the Caribbean: At World’s End	2007	$318m	$300m
3	Titanic	1997	$274m	$200m

Cleopatra was the highest grossing film of 1963, earning US $26 million ($57.7 million total), yet made a loss due to its cost of $44 million, the only film ever to be the highest grossing film of the year yet to run at a loss.
