Revealing mistake: Right at the beginning of the movie, an alien blasts Lieutenant Smalls and he drops his rifle. The weapon wobbles, revealing it's a rubber prop rifle. (00:01:55)
Continuity mistake: While racing through a parking complex to get to his daughter at the hospital, Lin ramps out of the exit and hits the font of his car on the ground leaving some damage, and even a part of the bumper hanging off. However in subsequent shots, the vehicle is undamaged. (00:02:50)
Other mistake: The Space Agency is trying to use an android mechanism (Human 2.0) to go to The Void and make first contact. Their first attempt at putting a human brain into the android fails. The solution is to make the android mechanism imprint human cells to facilitate the brain/android connection. The Agency is up against a time constraint, and someone comes up with the idea of using military Humans 2.0 to go on the voyage. Wait a minute! So now we learn there are other Humans 2.0 in existence? Wouldn't whoever made those already know how to solve the human brain/android interface? Why is the Space Agency reinventing the wheel?
