X-Men: First Class has been revealed as the most error-strewn movie of the year so far.

The origin story, starring James McAvoy and Michael Fassbender, tops MovieMistakes.com's annual rundown of blunder-filled pictures with 24 errors.

Howlers include a wrongly-dated Nazi coin, a character's hand changing position after being stabbed and pinned to a table with a knife, and an actress's hairstyle changing mid-scene.

Pirates of the Caribbean: On Stranger Tides came in second, with 13 errors such as a plate full of cream cakes appearing in the middle of a scene, and a court-room judge banging a gavel - even though they've never been used in British judicial history.

Sci-fi comedy Paul takes third place with 12 mistakes, and Super 8 and The Green Hornet share fifth spot with 10 errors each.
