O' Leary once stated that it was "remotely" possible some footage from the Apollo moon missions could have been created in a studio environment to avoid embarrassment on NASA's part. This started a controversy over O' Leary's beliefs whether the moon landings were real or not. In March 2001, O'Leary later appeared briefly in Fox TV's "Conspiracy Theory: Did We Land on the Moon," stating that "I can't say for sure 100%, whether these men walked on the moon. It is possible that NASA could have covered it up, just in order to cut corners, and to be the first to allegedly go to the moon." This has been a question of many hoax advocates for years but O' Leary remains quiet about the Moon program and has "no interest" in rejoining the debate.
