Other mistake: When Larry is taking the cigarettes out of the box, look at his hand. It has a white paint drop or white dust on it, but throughout the scene it disappears and reappears. (00:55:10)
Other mistake: When Adam is saying to Dr. Gordon "What I saw was you get into your car, that's it," Leigh Whannell's natural Australian accent slips through on the last two words. (01:18:09)
Other mistake: When you see the shot of the camera watching Adam and Dr Gordon, you can see a plank sticking out directly in front of the camera. A little later, when you see the camera's view, which has some incredibly wide views, you can't see the plank, which would definitely have to be visible to see both of the people in the bathroom.

Other mistake: Adam couldn't have been asleep underwater without dying. (00:01:00)
Suggested correction: He wasn't asleep, he was unconscious, and woke up as soon as his head slipped underwater.
