The trailer is pretty darn freaky, I actually liked it. Supposedly the footage in the movie "was found," and is not theatrical makeup. I don't know, it sounds kinda fishy to me. Maybe Michele, here, can answer it for you. LOL.
Here's the description from the trailer's YouTube page:
Apollo 18 is a found footage-style film set in December 1974, about a post-Apollo 17 mission to the Moon that takes on a premise of why NASA discontinued the Apollo moon missions. The plot involves a government coverup of the Apollo 18 mission after parasitic lifeforms on the Moon discovered the crew and began to attack them. Much of the back-story remains unknown; however, the movie posters in English indicate the Russian KGB role in Soviet lunar conspiracy and the Russian movie posters show inscriptions in English suggesting an American government cover up in lunar conspiracy. In the trailer, an American astronaut finds a dead cosmonaut and a Soviet LK Lander on the lunar surface.
In an interview with Entertainment Weekly, Dimension Films head Bob Weinstein denied the film was a work of fiction, stating that "We didn't shoot anything, we found it. Found baby!". This claim was met with some skepticism. The film will be distributed by Dimension Films.
