Filming on The Hobbit has hit another delay as director Peter Jackson was admitted to a New Zealand hospital with acute stomach pains, reports Heat Vision.

Peter Jackson underwent surgery Wednesday night for a perforated ulcer, according to a statement from the production. He is said to be resting comfortably, and doctors expect him to make a full recovery.

"Sir Peter's surgery is not expected to impact on his directing commitment to The Hobbit beyond a slight delay to the start of filming."

Filming was scheduled to start sometime next month.
