Continuity mistake: Billy tells Freddie, "We only have one rule!" while extending his arms. A shot later, they're down by his sides. (00:30:01)

Continuity mistake: When Hespera and Kalypso push the glass vitrine away, it falls and shatters into a zillion pieces. Half a second later, there's not a single bit of glass around. There's a better angle of the immaculate floor when a guard jumps on top of a woman.
Continuity mistake: When the group fly towards the accident on the bridge, from the aerial angle there are barely no people next to the smashed red car; a second later, there's 10 people around. Furthermore, the cars behind in a V-shape position are different: silver and red swap to dark grey and brownish. And, last but not least, the blue car's right door is open in the aerial shot, but closed an instant cut later.
