Joe Dante Classic
10 July 2005 | by (London, England) – See all my reviews

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.
