NASA reaches its outer limit, LA Times
"But after initially touting "Apollo 18" as one of its upcoming fiction film collaborations, NASA -- which, for the record, says the last manned mission to the moon was Apollo 17 in 1972 -- has begun to back away from the movie. "Apollo 18 is not a documentary," said Bert Ulrich, NASA's liaison for multimedia, film and television collaborations. "The film is a work of fiction, and we always knew that. We were minimally involved with this picture. We never even saw a rough cut. The idea of portraying the Apollo 18 mission as authentic is simply a marketing ploy. Perhaps a bit of a 'Blair Witch Project' strategy to generate hype."
"For the viral campaign, the film's official website has a subpage that updates periodically with several documents from before, after, and during the mission. The latest documents are internal memos at NASA that show how they knew something was up."
