Visible crew/equipment: Just after Edouard goes outside and Marianne is left alone in the art studio, Marianne walks around the room and looks at some of the drawings, before resting on the couch. Right before she sits down on the couch, just as she extends her leg, a boom mic can be seen in the bottom right hand corner of the shot, briefly entering the frame. (02:12:48)
Other mistake: The sword champion is murdered in a dark room. Cut to Tarek Richards by his corpse. The room is still shrouded in darkness, which makes for a cool transition. However, when the camera pans out and someone (with an audible click) turns on the lights, you realise that the room is full of cops which up to that moment have been working in a dark room for no reason - and they have been doing things that require reading and writing, like collecting witness statements.
Character mistake: In the very first scene, in the first shot you see a sign in Spanish that says "NO PASE por orden del departamento de arquiologia". The correct Spanish word is arqueologia.
Continuity mistake: In the first meeting with the man with the hat, Ice puts one foot on the portable cooler, but the position of the foot on the floor changes when there's a cut. Even more obvious, when she steps in front of him, the tip of her red stilettos touch his feet, but at the cut their tips are distant, and she moves in with her right foot first, as opposed as before.

Other mistake: Despite Lena's cab driver and his wife both being Armenian, the wife's speaking Spanish.
Factual error: Hawking explains how time slows as one approaches a black hole's event horizon. To illustrate this a CGI-animated analog wristwatch is shown ticking away the seconds progressively more slowly. It's the kind of watch that ticks intermittently: once each second the hand sweeps one second-long increment around the dial and then waits one more second to sweep another increment. In the animation, the frequency of the ticks lessens, but the speed at which the hand sweeps each increment stays the same. To be consistent, the sweep-speed needs to slow down just as much as the tick-frequency. (00:36:30)
Continuity mistake: When Jason and The Count duel, the cut on Jason's cheek is already there before The Count cuts him there. By that point, Jason was only cut on the shoulder.
