I think the most expensive movie ever was Avatar at about 150 mil,where do you guys come up with half a beelion?
From Wiki,(and yes, I know Wiki is not the know-all be-all truth teller) but here's what they list...
"Due to the secretive nature of Hollywood accounting it is not clear which film is the most expensive film ever made. Spider-Man 3 officially holds the record with an acknowledged cost of $258 million, while Pirates of the Caribbean: Dead Man's Chest and its sequel Pirates of the Caribbean: At World's End were produced together on a combined budget of $450 million, making them the most expensive production. Although the Pirates of the Caribbean sequels shared many costs it is estimated that around $300 million was spent on producing At World's End. More recently there have been reports that Avatar is the most expensive film ever made with speculation that it cost $280 million."
