Sir Peter Jackson has surgery for perforated ulcer

Sir Peter Jackson has undergone surgery after being admitted to Wellington Hospital with acute stomach pains.

The New Zealand filmmaker went to hospital on Wednesday night and had surgery for a perforated ulcer, The Hobbit publicist Melissa Booth said.

He is currently resting comfortably and his doctors expect him to make a full recovery.

Ms Booth said Sir Peter's surgery is not expected to impact on his directing commitment to The Hobbit, though there will be a slight delay to the start of filming.
