Director Adam Wishart spent a day filming members of the Artemis Society International (ASI) at their conference in a hotel across the road from NASA Houston. They were working on a commercial mission to build a moon base. At the end of filming, Wishart told the group - "Either you guys are bloody good actors, or..."
Gregory Bennett, president of ASI at the time quickly leaned back and said "That wasn't acting." Acting or role-playing had been discussed briefly by the attendees, but that was rejected, and they decided to just be 'normal'.
