Credit director Richard Mailer for coming up with an idea that no one else has ever tried before (as you read on, you'll figure out why).

A horny alien lands on earth and decides to inhabit the elevator of an office building. Then, as people ride up and down the possessed dumbwaiter, the alien turns on his sex beam and sends everyone into a sexual frenzy (now do you see why?)

OK. So the plot is inane. And the camera work and special effects (particularly the audio) are pretty typical. But Stacey Donovan is on fire as the elevator repair lady (and past president of her local UFO chapter) who comes on the scene (and just about everywhere else) to save the day... or does she?

Either way it doesn't really matter. She performs great in a three-way with Candie Evans and Joanna Storm in the alien's maiden voyage, as well as in pairs with nerd-turned-stud Francois Papillon and office manager Frank James. Joanna Storm is also hot in the elevator scene, and really ignites the 2-on-1 finale with Ray Wells and Randy West.

The rest of the sex is average, but you'll want to see this tape for beautiful Donovan and lovely Evans. The other people who take part in these extraterrestrial love tussles (like Keli Richards' "disgusting" men's room boff and Tom Byron and Natasha Skyler's elevator trip) do one scene and are gone. This is no way to build characters and/or a story. But for sexual purposes, Up All Night will keep you up all night!
