Director Michael Bay's action-packed Transformers: Dark Of The Moon has been named the most mistake-ridden movie of 2011.

Eagle-eyed film fans have reported 58 blunders in the third installment of the Shia LaBeouf release, six more than the latest Pirates of the Caribbean sequel, On Stranger Tides.

However, the big franchise films aren't the only ones named and shamed in MovieMistakes.com's end of year poll - X-Men: First Class (30 mistakes), Harry Potter and the Deathly Hallows: Part 2 (20 mistakes), and Super 8 (17 mistakes) are also filled with errors.

Website creator Jon Sandys also highlighted a few of his favorite flubs:

- In the first scene of Transformers: Dark of the Moon, Carly is wearing a white cap as she heads up the stairs, but the hat is gone when she is shown holding a stuffed rabbit.

- Bradley Cooper accidentally calls his The Hangover Part II co-star Ed Helms' character Stu "Ed" as they flee the Russians with the monkey.

- In The Twilight Saga: Breaking Dawn - Part 1, when Bella calls Rosalie, the cell phone screen can briefly be seen before she puts it to her ear. The keypad lock screen is still visible, showing she didn't dial anything.
