Revealing mistake: As Jaime starts 'cutting' along the window with her bionic fingernail, the precut outline is quite visible from the sides, and her left hand is resting on the ledge of the first hole she cut, to give her leverage.

Revealing mistake: The wires holding the small satellite the two alien men are 'channeling' across the lake are visible although it's supposed to be floating.
Revealing mistake: After Max the dog breaks free from the cage and then bites through Callahan's chains, the two head to the metal barred window and Max begins pulling on one of the bars with his teeth. Which are obviously rubber, as they 'bend' slightly as the dog is pulling.
