One of the funniest aspects of Innerspace is how elaborately over-plotted it is. Go to Full Review

3/4
''Innerspace'' is a classic example of a film that would achieve more if it tried less. But it still is an ambitious comedy made funny by Short's sweet performance... Go to Full Review

3.5/5
Innerspace may seem like nothing more than a silly riff on Fantastic Voyage, but in utilizing a rather unique & absurd approach, as well as stunning Oscar-winning visual effects, it manages to become a rather entertaining adventure. Go to Full Review

4/5
Joe Dante's comic sci-fi /action romp still holds up as a crackling adventure bolstered by the odd-couple conversational chemistry of Dennis Quaid and Martin Short. Go to Full Review
Richard Freedman Newark Star-Ledger Jan 12, 2026
Most of "Innerspace" is derivative, with little invention of its own. Go to Full Review

Hagrid W Feb 2, 2019 Having seen this a long time ago, I completely forgot that it existed. So, refinding it on a 10 cent VHS tape, not in a surprising way, but more of an "Oh Yeah, this exists" kind of way, had me wanting to watch it again. Although through my weird memory I somehow forgot Martin Short was in this. Innerspace is about a ride at Disney world, I mean a redo of Fantastic Voyage... wait, nope it's both! Dennis Quaid is a drunken fighter pilot who gets injected into Martin Short's spastic everyman body. Short must find a way to get Quaid and his little machine out of his insides before an evil group of evil scientists take him out....permanently! It's fun and goofy and way-way too long for this premise. Side plots with the buyer of stolen goods "The Cowboy" seem like filler and although Quaid and Short have great chemistry which lasts for the whole film, Short's spastic routine isn't really my cup of tea in this film. The Quaid Meg Ryan relationship was fine, but also seemed like it was added in just to pad out parts of the film. As I said, while entertaining, Innerspace adds up to a lot of running around, chase scenes, and Short dancing like his bones are breaking at the same time. I still found it to be mostly entertaining though, and I would recommend it if you haven't seen it. But, the overall length and the side plots just kept it from being great. See more
Albus P Feb 2, 2019 I was expecting more.I do not say the film is bad, on the contrary, the film is very good, the actors are good, the story is very funny and interesting, the jokes are great and the action scenes are fantastic, I just did not like the slow progression of story that makes the story a little captivating and a bit boring, but even so, the film had a lot of fun and I highly recommend it.

Theodore S Sep 22, 2018 Visually impressive and pretty dang funny thanks to Martin Short, this sci-fi adventure is nonetheless reduced to B-level due to its campy serial-style plot. See more
Hagrid R Aug 23, 2018 With all of the parties involved in the making of this film, it was clear that there was a desire for it to achieve blockbuster status. Whereas it's a good film, it doesn't quite get to where it could be, in part due to an overabundance of 1980s slapstick and hokey comedy. The special effects are genuinely interesting when you consider the year in which it was all done. An interesting concept that could have been so much more. See more
Rey L Feb 13, 2018 An awesome adventure the whole family can see.
Abraham W Dec 26, 2017 original and fun to watch. The props are well done making it still enjoyable today. A must see film.
