BRAD PITT’s  over-budget, over schedule, and under-developed zombie flick in big trouble so he gets LOST.

No, he doesn’t get all jazzy – reportedly he enlisted the co-creator of LOST Damon Lindeloff to help him with his flagging vanity project.

The belagured film is based on Max (son of Mel) Brooks' book "World War Z: An Oral History of the Zombie War."

Lindeloff told glam mag Vanity Fair how Brad had painted himself into a creative corner.

“We started working on the script, a lot of that stuff had to fall away for the story to come together. We started shooting the thing before we locked down how it was going to end up, and it didn’t turn out the way we wanted it to,’” Lindelof says Pitt told him.

Lindelof said that Brad wanted fresh eyes on his undead baby – directed by Marc Forster.

“'The thing we really need right now is someone who is not burdened by all the history that this thing is inheriting, who can see what we’ve got and tell us how to get to where we need to get,'" Lindelof said of Pitt.

The movie, which was initially set for a December 2012 release, was forced to re-shoot nearly 40 minutes of film after execs reportedly said it stunk.

The film’s budget has now soared to over $200 million.
