When they crash land on the alien planet, in between scenes there is, then isn't, smoke from their crashed craft blowing past them.
When Adler kills the alien, the latter ends up face-down. In the next shot his body is face down, but his had has been turned to his left, facing Adler.
In the 67th minute, it seems unbelievable that the alien, if adept at using his own weapon, would miss Adler with five point blank shots.
The second alien fails to kill Adler with many shots, but she manages to kill him relatively easy with his own weapon, a weapon foreign to her.
Close ups of technical displays within the cockpit are shown several times as the crashed ship attempts to power up. The text is clearly legible, and shows a Linux computer boot sequence. Date and time stamps are visible, ranging from 2008-2013. Not exactly contemporary for a futuristic, hyperspace-capable space fighter.
A space craft that takes off along the ground, like a plane, seems uniquely antiquated for space travel.
