Apollo 18 (2011)

 

Decades-old found footage from NASA's abandoned Apollo 18 mission, where three American astronauts were sent on a secret expedition, reveals the reason the U.S. has never returned to the moon. 

OK sci-fi horror with a rather standard plot, but made more interesting with its "found-footage" approach; unfortunately, the existence of the "aliens" is not much explained.

Maltin**: "Plodding sci-fi thriller attempts to inject fresh life into familiar scenario...by mimicking the "found footage" semidocumentary approach...Viewers old enough to have watched original Apollo space flights on black-and-white TV may be mildly amused by moments of visual verisimilitude. Overall, though, entire production comes off  as little more than a modestly clever stunt."
