'Indiana Jones and the Kingdom of the Crystal Skull' has become the most mistake-ridden movie of the year - after cinema-goers spotted over 40 bloopers in the new film.
Observant visitors to website MovieMistakes.com have noted a variety of continuity errors and historical inaccuracies in the fourth installment of the adventure franchise, which include the explorer's shirt appearing tucked and untucked in a single scene and an American flag with an incorrect number of stars.
Website owner Jon Sandys admits he isn't surprised.
He says: "Any film set in the past always has a potential extra set of problems on top of regular continuity mistakes.
"In addition, there are so many Indiana Jones fans that this movie's going to be scrutinised a lot more closely than some others."
Action movie 'Iron Man' is the second most error-filled movie, with 15 reports of mistakes listed.
