Did You Know?


The lab workers seen during the scene where Dennis Quaid is about to be miniaturized were in fact real laboratory workers, as actors would not have been suitable to performing what real lab rats do.


Factual errors:
Tuck's mini computer keyboard has a slightly altered QWERTY layout. "Z" is found to the right of "L" and under "P" – which arguably may not be a goof even if it would make typing difficult – but the bottom row reverses the usual placement of "V" and "C" as well, which has to be purely a mistake.

Eat me, drink me? What is that? From The Exorcist? No, Alice in Wonderland! Alice she drank something to be big and ate something to be small.

User Review

Joe Dante Classic

Rating: 10/10

This 1987 film is a wonderful combination of sci-fi, comedy, romance
and thriller elements. It is briskly paced despite being almost two
hours in length, and features superb performances from the leads;
Dennis Quaid is excellent as usual, as is Meg Ryan in her best role.
Yet the plaudits must go to Martin Short in a truly great performance
he has never matched. He just needs the right role. The supporting cast
are great as well; the delightful villainy of Vernon Wells who is
unrecognisable as usual! Also Robert Picardo camping it up superbly as
The Cowboy, one of his most memorable creations, plus the great pairing
of Fiona Lewis and Kevin McCarthy, who memorably says to his dog before
feeding it: 'Never beg, never beg!' The cinematography and special
effects/makeup are all great as well, and Jerry Goldsmith's score is
brilliant, perfectly complementing the tone of the film, alternately
exciting/sprightly/romantic. Joe Dante binds it all together with
magnificent verve, plus Dick Miller makes his trademark appearance! A
great, timeless classic. Highly recommended.
