X-Men: First Class is leading a Hollywood list of shame - it's the most mistake-filled film of 2011 so far.
 
At the halfway stage of website MovieMistakes.com's annual rundown of blunder-full pictures, the superhero blockbuster - starring James McAvoy - leads the field with 24 errors.

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

Pirates of the Caribbean: On Stranger Tides is second in the list, with 13 mistakes including a plateful of cream cakes suddenly appearing in the middle of a scene, and a court judge banging a gavel - they've never been used in British courtrooms.

Third in the list is sci-fi comedy Paul, with 12 errors, with Super 8 and The Green Hornet tying for fourth place with 10 mistakes each.
