If you loved Innerspace, try Amazon Women on the Moon
A bridge between a film you've already seen and one most people haven't. Amazon Women on the Moon has roughly 7.6× fewer votes than Innerspace — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Joe Dante, and they both carry the neon soaked mood tag, and they sit in Comedy / Science Fiction territory. If that's the register that drew you to Innerspace, the second film will land in a comparable space — through a different lens.
What Amazon Women on the Moon is
A series of sketches loosely masquerade as a film. The wraparound involves a TV station airing a low-budget 1950s science fiction film, complete with goofy commercials and oddball shorts. It certainly has a go at skewering pop culture.
