Following in the wake of James Cameron's Aliens (1986), many a suck-arse Aliens-in-space movies were made to capitalize on its success. Well, I was about to say "Forbidden World is one of those" then luckily I noticed the year: it was made 4 years before Aliens. So, Forbidden World is NOT one of those. Nonetheless, it still sucks arse.
It does, however, has Dawn Dunlap naked in it. So, you see, there is a bright side to everything.
Remember David Hamilton's Laura, les ombres de l'été? It was Dawn Dunlap's screen debut. She was only 17 at the time and her naked young body was an absolute delight for the eyes!! 3 years later she appeared nude again in Forbidden World, again lighting up the screen with her bare boobs and butt and some flash of bush.
UK actress June Chadwick also has a sex scene but it's very badly edited and poorly lit.
The shower scene with both of them in it is very nice, though.
