Continuity mistake: When Tony goes after the nuke, there is a huge cut visible above his right eyebrow (or viewer's left). Later on after his face mask is removed, his right eyebrow is completely visible in the shot, even with the helmet in the way, and the cut is nowhere in sight. (02:00:00 - 02:03:00)

Casual Person

Continuity mistake: During the battle of New York, Thor has just landed next to an upturned silver car. The rubble around the car changes/moves. The most noticeable is one wedged next to the front right wheel. The piece becomes much bigger in the next shot. (01:50:25)

Sacha ★

Continuity mistake: Capt. America has just destroyed the first punching bag and walks away to pick up a new one. There are now 5 bags left. Note the chains belonging to the third one from the left. The way they lie on the floor differs in from shot to shot. (00:21:15 - 00:21:55)

Continuity mistake: In the scene where Loki escapes with Hawkeye and Agent Hill is chasing them, she does a 180° spin and ends up face to face with Loki's driver. She shoots through the glass and you can see the bullet hole, but during the rest of the scene, the hole is gone. (00:09:25)

eructo666

Continuity mistake: When Thor says "I have unfinished business with Loki", you can see Hawkeye in the background removing the spent heads of his arrows, four of them, two a little lower then the rest. The shot cuts, and he is holding all four at the same height. (01:46:05)

Friso94

Continuity mistake: Throughout the film, Tony Stark's chest ring can be seen glowing through his shirt except for two occasions when it's suddenly off - after Loki escapes from the helicarrier, and when Loki and Tony Stark are talking in Stark tower, even when he's wearing the same shirt. (01:35:30)

Trivia: The Avengers co-creator Stan Lee makes his usual cameo. This time as a man being interviewed by a news reporter asking about superheroes, at the end of the movie.
