I couldn't believe it. I had to rub my eyes a few times. Was it true? Yes, there were Billy Dee Williams, Jeff Conaway, Maxwell Caulfield and Tracy Scoggins - all of them have some manner of talent but here they all were in what basically adds up to a Cinemax-style skin flick set on board a spaceship!Sad as it is, "Alien Intruder" tries to be unique, with a computer virus/alien demon/harpy/whatever else you want to call her named Ariel (Scoggins) infiltrating this sort-of high-tech virtual reality station on board a spaceship where four men are allowed to live out their fantasies as the system is over-seen by their captain (Williams).Interesting? Maybe, but here everything just plays out like a well-padded episode of "Red Shoe Diaries". Williams out-classes everything right and left, and looks like he'd rather be doing anything else, ANYWHERE else. Ah, the things people do for money....The FX are pretty static, maybe even less than what you'd expect for a straight-to-video cheapie like this. Unfortunately, even the female nudity is less than you'd expect. SEXUAL INNUENDO is the real star here and, of course, it gets ALL the best scenes.If you like a movie that's all tease and no brains, check out "Alien Intruder". Of course, you'll probably have to look no further than Cinemax at 2 or 3 in the morning.No stars, not even for what star power this flick can muster.Leave this one lost in space.
