Continuity mistake: Tenaya 7 is running on the treadmill in flat sandals with tan straps, she then has flat sandals with black straps as she fights the guards.
Revealing mistake: When Chloe, Eli, Greer, and the rest of the team first go to the alien planet, you can see a car driving in the background to the left of the screen at the beginning of the shot (which wouldn't make sense considering they're on an alien planet). (00:15:40)
