Monolith (1993)

Two cops (Bill Paxton & Louis Gossett Jr.) are investigating the murder of a young boy in Monolith (1993).  As the investigation goes on, they become involved in a secret project involving aliens.  What? Anyhow, as is usually the case, the government wants this secret project to stay secret and do their best to make sure our heroes can’t solve this multi layered mystery.

Bill Paxton gets a chance to show off his tight terrestrial tush in one skinlicious shower scene.  We get a close encounter of the full back nudity kind and there are sings of throbbing life below the belt as the camera lingers on his smooth, taut butt and muscled back.
