Joe Dante directs Dennis Quaid, Martin Short and Meg Ryan in an action comedy about a hypochondriac store clerk who has to rescue the minitaturised test pilot who has been injected inside him. 

A summer blast, so full of neat ideas and well executed wonderment that you can’t help but be won over by it. There are about half a dozen movies fighting for dominance here (a Fantastic Voyage update, a Spielbergian Amazing Tale, a paranoid chase movie, a Meg Ryan romance, a Martin Short broad comedy and a Joe Dante live action Looney Tunes jamboree) yet the pace never slips and it rarely tips over into messiness. A busy romp but busy with pointedly entertaining elements. Most importantly for a high concept flick like this the internal FX work is convincingly gloopy and awe inducing while the set pieces, both within and without the body, prove to be consistently kinetic and intense. Add to that some killer use of soul singer Sam Cooke and you have a winner, lacking any rust or wear three decades on.
