Peter Jackson's dramatisation of The Lovely Bones has become the most complained-about film of the past year.
The British Board of Film Classification (BBFC) said the 12A-rated film prompted the biggest postbag of the year in 2010.
The film is about a murdered girl who watches over the lives of her family and her killer from the afterlife.
"Many found it to be a shocking and upsetting experience," the BBFC said. According to the BBFC's annual report, the film – based on Alice Sebold's novel – was "right on the borderline" between a 12A and a 15.
