Peter Jackson's lastest movie The Lovely Bones has had a change of leading actor on the eve of filming.

Canadian Ryan Gosling has been replaced by Mark Wahlberg after what Variety magazine termed "creative differences."

The Los Angeles Times reported Jackson as being quite surprised Gosling had showed up to start work on the film looking like he'd donned a fat suit.

According to sources, the 26-year-old Gosling had apparently told the director he was going to gain weight to age himself up to play the part of a grieving father, but Jackson expected some movie star allure - not paunch and a beard, the newspaper reported.
