Still great fun, after all these years!
A really quite short movie (1hr 27 mins by my clock), that just gets straight to it, moves briskly through, in what a more highbrow critic might call "dumb fun", but suits me down to the ground.
A young Sean Astin is digging a hole in his garden for a pool, in order to up his cool factor at school, and accidentally unearths (with the aid of a minor earthquake, and chum Pauly Shore) a block of ice, with a cave man (Fraser) inside...
...He goes off to school, and upon his return, discovers the Ice has melted, and said cave man is loose in his house. Astin and Shore (Dave and Stoney) befriend him decide to modernise him, and take him to school and help them become popular. The uncivilised Fraser (Link) introduces a little anarchy and lots of amusing hijinks.
The basic set up of uncool kid seeking popularity, especially with childhood sweetheart, in opposition to school bully is certainly not new, and is indeed, a hang over from the eighties of the kind of John Hughes style teen drama, but for laughs.
Brendan Fraser's largely mute performance, bar occasional grunting, and the odd word, is charismatic and engaging nevertheless, even, at one point, quite touching, when he realises he's been stranded out of his time.
Even Pauly Shore gives a relatively muted performance, thankfully, as you can certainly have enough of that guy, and whatever that Schtick of his was back then.
For fans of said eighties teen dramas, but in a comedy sense, as well as movies like Airheads, Empire Records, and other throwaway cheap and cheerful, fun comedies of the nineties.
