A great piece of family entertainment
10 November 2011 | by (United Kingdom) – See all my reviews

One of those quintessential family movies of the 1980s, INNERSPACE turns out not to have dated a bit since it was first release. The story, which is heavily indebted to the '60s movie FANTASTIC VOYAGE, sees Dennis Quaid shrunk down to miniature size and injected into the body of super-nerd Martin Short. What follows plays out as a live action cartoon, which is no surprise with Joe Dante at the helm. Dante is one of those directors who doesn't know how to make an unappealing movie, and INNERSPACE is one of his most entertaining efforts.

I've never been a huge fan of Dennis Quaid, and his performance here is hardly endearing: he plays a rude, arrogant, loud-mouthed drunk for much of the film, and casting Meg Ryan as his insipid girlfriend isn't much help either. Still, I do like Martin Short, and his turn here is rather endearing and genuinely funny, especially when infused with the clumsy slapstick style of humour. Dante has a great eye for a supporting cast, fleshing out roles for the likes of old-timer Kevin McCarthy (a ball as the bad guy), Vernon Wells as the hit-man, Fiona Lewis, Robert Picardo as an unlikely cowboy and, of course, Dick Miller.

The script is light and airy and never lets itself get bogged down in science. The journeys inside the body are excellent and have all the imagination of an outer space classic. Finally, we get Rob Bottin contributing some literally jaw-dropping FX work, which rounds out the package nicely. The 1980s may well have been the decade that taste forgot, but they sure knew how to make a fun movie back then.
