Why no Moon return? ("Apollo 18" trailer)

(APOLLO 18) Officially, Apollo 17 -- which the US launched on December 17, 1972 -- was the last manned mission to the Moon. But a year later, in December of 1973, two American astronauts were sent on a secret mission to the Moon funded by the US Department of War (Defense). This movie claims to contain actual footage the astronauts captured on that mission. While NASA denies its authenticity, others say it is the real reason we have never gone back to the Moon.
