Cameron Diaz’s The Box has reportedly been named one of the worst films in history by movie fans.
CinemaScore, a company that compiles ratings for new releases, explained that an A means a picture is likely to be a big hit, while a C is pretty much a death sentence.
The Box, written and directed by Donnie Darko's Richard Kelly, was awarded an F.
"People really thought this was a stinker," the Sun quoted Ed Mintz from CinemaScore as telling the Los Angeles Times.
The only three movies he could recall scoring as many Fs were: The Bug, a 2006 Ashley Judd horror film; Wolf Creek, a 2005 backpackers-in-peril thriller; and Darkness, a 2002 haunted-house scarefest.
He put the negative reaction down to the film's controversial ending, asking: "Who'd want to pay 10 dollars (6 pounds) to see that? "I'd love to hear how they thought they were going to get good word-of-mouth."
In the movie, Diaz plays a cash-strapped mother who is promised that she will receive a million dollars if she presses the button on a mysterious box. When she does so, tragedies start happening - including her son going deaf and blind.
The Box bombed at the American box office and scored generally poor reviews from critics. However, the 37-year-old beauty defended her decision to make the movie.
"There is no much about humanity in the script and so much we are trying to understand about who we are as people," she said.
