Indiana Jones comeback tops blunders poll

'Indiana Jones and the Kingdom of the Crystal Skull' has topped a new poll of this year's most gaffe-prone movies - with a staggering 64 continuity blunders.

Harrison Ford's whip-cracking return to his hit adventurer franchise came first in a new survey by film website moviemistakes.com.

Fans spotted a huge number of mistakes in the Steven Spielberg movie - including the use of a Harley Davidson motorbike from 2000, despite the fact the film is set in 1957.

Other blunder-filled films include box office smash 'Mamma Mia!' and Heath Ledger's last full acting role as The Joker in Batman movie 'The Dark Knight' - with 44 and 43 mistakes respectively.

Jon Sandys, Moviemistakes editor, says: "With the budget of many movies, you'd think they could avoid mistakes like this, or at least use computers to cover them up, but they keep cropping up, and eagle-eyed movie fans keep spotting them."

The full list of 2008's continuity-challenged films is as follows:

1. 'Indiana Jones and the Kingdom of the Crystal Skull' - 64 mistakes

2. 'Mamma Mia!' - 44 mistakes

3. 'The Dark Knight' - 43 mistakes

4. 'Twilight' - 41 mistakes

5. 'High School Musical 3: Senior Year' - 41 mistakes

6. 'Journey to the Center of the Earth' - 31 mistakes

7. 'Quantum of Solace' - 23 mistakes

8. 'Get Smart' - 22 mistakes

9. 'Step Brother' - 22 mistakes

10. 'Iron Man' - 21 mistakes
