Revenge of the Spacemen (2014) [Blu-ray]

Revenge of the Spacemen descends onto earth in a flying saucer, to the disbelief of a few witnesses that spot the outer-space craft. Unable to convince other backwater locals that what they saw was more than an intoxicated hallucination, the witnesses embark on a mission to find proof of the extraterrestrial invasion. When the gang turns up a couple of missing backwater cretins who recount their tales of anal-probed alien abduction (compounded with a seriously out of this world case of gas), townspeople finally start to BELIEVE. The noxious gases go from unbelievable to unbearable, and it takes a boozy backyard standoff to eradicate the extraterrestrial BDSM terror!
