Critics Consensus

A manic, overstuffed blend of sci-fi, comedy, and romance, Innerspace nonetheless charms, thanks to Martin Short's fine performance and the insistent zaniness of the plot.

One of the funniest aspects of Innerspace is how elaborately over-plotted it is.

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...

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.

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.

Most of "Innerspace" is derivative, with little invention of its own.

Just another 80's movie. Deranged, unhinged, bad plot but decent acting. Not that good.

There’s something really fun about the entire premise of this movie. This dude unknowingly gets screwed over by some doctor that was getting chased, and now he’s gotta deal with some guy talking in his ear. It’s very fitting for Dante considering his track record with comedic sci-fi adventures. 4/5 stars.

I wasn't highly invested in this. Has strong moments and Quaid is awesome. Really felt highly forgettable and mediocre. Left feeling like I could have seen something else instead lol.

Such an imaginative, fun, unique, entertaining movie! Great charismatic cast. A core 80's family, sci-fi, adventure film with some average Joe characters not set in space but in a science lab. It's both silly, strange, and sensitive. Doesn't get the credit it deserves. Who doesn't love frickin Dennis Quaid and Meg Ryan when they were a couple?? And Martin Short is unforgettable, especially when shown as a regular guy, who's funny but not a comedy heel. So glad this came out when I was a kid.

I was really into Innerspace when I was a kid. I loved the concept, I thought it was exciting, it made me laugh, it had everything. It wasn’t until I grew up that I realized how bonkers of a movie it really is. The plot is really far out there, and there are parts of it that don’t really make sense. And yet, it’s still exciting and funny. If this film were made today, it would be entirely computer generated, but the practical effects actually help it hold up better. Martin Short is amusing, Dennis Quaid is charismatic, and Meg Ryan is adorable. Despite its shortcomings, I still enjoy Innerspace.

This movie should have been a massive box office smash.
