A Funny Thing Happened on the Way to the Moon is a 2001 film written, produced and directed by Nashville-based filmmaker Bart Sibrel.

Sibrel is a proponent of the conspiracy theory that the six Apollo Moon landing missions between 1969 and 1972 were elaborate hoaxes perpetrated by the United States government, including NASA.

Sibrel proposes that the most condemning evidence is a piece of footage that he claims was secret, and inadvertently sent to him by NASA; he alleges that the footage shows Apollo 11 astronauts attempting to create the illusion that they were 130,000 miles (210,000 km) from Earth (or roughly halfway to the Moon) when, he claims, they were only in a low Earth orbit.

The film's premise is that NASA perpetrated a fraud because of the perception that if the United States could land men on the Moon before the Soviet Union, it would be a major victory in the Cold War, since the Soviets had been the first to achieve a successful space launch (Sputnik 1 in 1957), the first crewed space flight (Vostok 1 in 1961), and the first spacewalk (Voskhod 2 in 1965).
