The Twilight sequel has become the latest victim of eagle-eyed film fans reporting to website MovieMistakes.com - they've spotted 17 grave errors in the vampire versus werewolves movie.
The mistakes range from vampires' contact lenses on display during the movie's climactic fight scene to blunders about the use of the wrong plane.
Website editor Jon Sandys explains, "When Bella (Kristen Stewart's character) is flying to Italy, they show a Virgin America airplane.
Virgin America only flies within certain cities in the US. Virgin Atlantic flies from the U.S. to Europe."
