The budget for Brad Pitt's World War Z became "insane".
The zombie movie cost around $200 million to make after requiring an extra 40 minutes of footage be shot in order to give it a coherent ending, and due to the various problems that plagued the set.
At one point at the end of production for the film in Malta, the crew found a number of purchase orders totalling millions of dollars which had been forgotten about.
Marc Evans, President of Production at Paramount, calls the oversight an "unthinkable action".
He explained to Vanity Fair magazine: "It was literally insane. Adam [Goodman, President of the Paramount Film Group] and I believed we'd gotten out of Malta good, and I found out we weren't. That is a nightmare."
