Continuity mistake: When Joseph Gorden-Levitt is performing his street act in Paris, somebody drops a jaw-breaker candy into his hat instead of money. He removes the jaw-breaker, performs some sleight-of-hand with it for the entertainment of the crowd, then deftly drop-kicks the candy into his mouth and bites down on it hard on the right side. It breaks his tooth and he immediately goes to the dentist; but he is clutching the left side of his face, instead of the right side.
Continuity mistake: In the locker room scene after Tony injures his knee, Tony walks outside the room crying and he then throws his helmet against a wall, causing the chin strap to fall off onto the floor in front of the the doors.

You can see a quick glimpse of the chin strap back on the floor where it was before.

The next view of the shovel shows it has fallen to Ilya's left. (The entire shovel is to the right of Chris, which would be too far regardless of which direction the shovel's handle fell.) In the next view, the shovel's blade is opposite Chris' left foot and later the angle is different. (00:36:30)

Continuity mistake: Spoiler alert: About halfway through the movie, we see Emma Roberts coming out of the shower, and the camera focuses on the gunshot wound on her shoulder, with the round scar of the entry wound on her back, and the much rougher, ragged scar of the exit wound on her front. Then at the end of the movie, where it's revealed that Kiernan Shipka and Emma Roberts were actually playing the same character, just nine years apart, Kiernan Shipka gets shot by the police officer when he finds her in the room with the severed heads. Problem is: she was facing the officer. The scars on Emma Roberts are the wrong way around. (00:31:05 - 01:15:35)
