Continuity mistake: Sean and Emily spend the night on a boat after her first mob. The blanket lies differently in consecutive shots. (00:45:25)

Continuity mistake: At the bar, just after Emily's first flash mob, Sean alternately has his right arm around Emily's shoulder and not. (00:41:20)
Continuity mistake: In the scene where they dance in the restaurant Emily's mask is for a second higher than before. It is a moment after she is put on the other table and the Asian guy is going the spell 'the mob' with the knives and forks.
Continuity mistake: Emily is wearing two tops while attending dance class, a dark blue one on top of a black one. The way their straps lie on her shoulders are different. (00:49:35)
