The consultation by N.A.S.A. scientists was requested before the filming of this movie, but N.A.S.A. stated that the events in this movie were too ridiculous actually to occur, and denied the request. N.A.S.A. sent a memo out to all of its employees stating that they were not allowed to comment on the likelihood of the events portrayed, but later rescinded this restriction.
