Penelope Cruz and Tom Cruise in 2001's "Vanilla Sky."

Tom Cruise's confusing movie Vanilla Sky has been branded the most baffling film in a new poll.

The 2001 movie, which stars Cruise as a playboy left horrifically disfigured after a crash, was the film which left audiences most perplexed by its plot.

According to the survey by LoveFilm.com, David Lynch's surreal thriller Mulholland Drive was voted into second place, while the sinister rabbit in Donnie Darko prompted cinema-goers to put it at number three.

The top five brow-furrowing films were rounded out by The Matrix Revolutions and Christopher Nolan's Memento.

Other movies to make the list include 12 Monkeys, Eternal Sunshine of the Spotless Mind, 2001: A Space Odyssey, Revolver and cult classic A Clockwork Orange.
