Since 1969, there have been plenty of convincing debunkings that the Apollo 11 moon landing was faked, from the tireless and exhaustive work of the folks at Moon Base Clavius to Buzz Aldrin landing a solid right jab to the face of lunar truther Burt Sibel.

But one of our favorites has to be this short film from S.G. Collins, posted back in 2012 and making the rounds once again this week. Collins, a filmmaker himself, does a very good job of laying out a simple truth: In 1969, America had the technology to strap three men to a rocket and then land them on the lunar surface. What America didn't have was the filmmaking technology to convincingly fake that event. As Collins put it, "people forget how primitive video technology was."

It's a 13-minute watch, but Collins has a kind of Deputy Dog deadpan thing going on that makes it surprisingly watchable. The good tech bits begin around the 4 minute mark, but all of it is worth watching—particularly if you ever want to shoot down a lunar truther in your own life (and, unlike Buzz Aldrin, you don't want let your fists do the talking):
