There are two flags on one character's Air Force uniform - one on each shoulder - and neither is correct. The one on the right should is backwards and the one on the left shoulder is upside-down.
In one scene they use a car to drive out of the ships cargo holed running the vehicle in a vacuum.
At one point in the movie an actors space suit sleeve pulls out of his glove showing bare skin.
The credits show one of the characters listed as "Pvt. Malcolm Neiman", but on screen the name tag on the character's uniform shows "Malcolm". The name shown should be the character's last name. Also, the character identifies his rank as PFC while the screen credits list the character as "Pvt".
