Apollo 18 (2011)

Factual error: When Nate dies by the alien moon rocks, his helmet visor "explodes." The visor in the film shatters like glass, but the real visors on actual spacesuits are made of polycarbonate, a plastic that does not shatter but deforms.

Plot hole: How would any of the EVA/16MM video footage be recovered in the first place? Astronauts took pictures like these on rolls of film, and those were developed well after the end of the flight. If the spacecraft had not been recovered at all, then the footage would simply be a piece of orbiting space junk. (01:22:40)

Revealing mistake: Whenever the astronauts are outside the module they are affected by being in a lower gravity environment. However, when inside there seems to be no effect, an example is when the helmet falls.
