Bart Winfield Sibrel (born 1964 or 1965)[1][2] is an American conspiracy theorist who has written, produced, and directed films arguing that the Apollo Moon landings between 1969 and 1972 were staged by NASA under the control of the CIA.

Sibrel has been a director of TV commercials[5] and is sometimes identified as a maker of "documentaries" with respect to his self-released Moon landing denial films,[3] though other sources point out the personal distribution, limited release, and style and content call into question placing Sibrel's work in this genre of filmmaking (e.g., with the St. Petersburg Times and The New York Times placing the word documentary in quotation marks in some of their reports).

[5][6] This concern relates in part to Sibrel's record of misrepresenting his identity to the subjects he attempts to interview, notably repeated attempts involving former astronauts including Buzz Aldrin, Neil Armstrong, Alan Bean, Eugene Cernan, and Edgar Mitchell (where Sibrel posed as filmmaker associated with the History Channel).

[5][3][4] As of 2002, Sibrel was operating a video production company in Nashville, Tennessee, and had "made a career out of perpetuating the notion that NASA's Apollo moon missions were hoaxes.

"[5][6] Sibrel confronted several Apollo astronauts in the preparation of his videos,[3] all of whom responded indifferently or negatively when they realized that they were being challenged on their achievement of landing and walking on the Moon.

"[4] By Aldrin's account, he went to the Beverly Hills hotel on that date under the pretext of an interview on space for a Japanese children's television show.

"[5] As described by Eric Spitznagel for Popular Mechanics, since "witnesses testified that Sibrel had provoked [Aldrin], assault charges against the former astronaut were dropped".

[4][3] In July 2009, Sibrel, who at the time was working as a Nashville taxicab driver, was charged with vandalism when he jumped up and down on the hood of a car owned by a woman with whom he was having a parking dispute.
