Apollo 18, pretty freaky and very intense. I even let out a startled cry during the movie. "Decades-old found footage from NASA's abandoned Apollo 18 mission, where two American astronauts were sent on a secret expedition, reveals the reason the U.S. has never returned to the moon" (imdb.com). The alien weren't even your typical aliens, which was good. The movie was shot in the style of old film to give it a 1973 look.
Three astronauts were sent to space on Apollo 18 under classified and never made know to the public. The movie was edited from 80 hours of footage uploaded to the internet (I can't remember/find the site they referenced). Two of the men went down to the surface of the moon to setup listening posts (as they were told) to watch for Soviet missiles. In the movie, it points out movie rocks and weird things as they go along. Well the men find an abandoned Soviet lunar lander, evidence that the Russians had made it to the moon. They find the body of the Cosmonaut at the bottom of a crater and pull him up. They find a strangeish rock in a rip of his suit. Finishing their mission, as they are about to lift off, the power and communications cutoff and on. The communications remain off because the radio has been tipped over. As one of the men go out to fix it, he starts screaming and saying their is something inside his suit and goes down. The other man goes out to get him and bring him back in. They discover he was cut by something and has a rock under his skin in the cut and get it out (gross because one of the guys says that it starts moving). Anyways, they cant get off the surface and are having troubles while they guy who was cut starts to act crazy and gets sick.
This movie was super intense and crazy. I really liked it. There was a historical element and a horror element mixed together and the "aliens'' were not your typical aliens. The aliens were like spider/crab things and you never got a good look at them, which heightened the suspense of the movie. And one of the guys was pretty good looking, Warren Christie. The movie is rated PG-13 for like horror and brief language and intensity, probably not one for little ones.
