Amazon.com video review:
Distractingly loose but clever, this 1987 comedy by Joe Dante
(Gremlins, Matinee) stars
Martin Short as a hypochondriac and Dennis Quaid as a miniaturized
test pilot who is accidentally injected into him. Taking a page or two
(or a hundred) from the classic science fiction movie Fantastic Voyage,
Innerspace details the adventures of traveling through the
human body's complicated systems, though in this case, it proves an
unusual way for two characters to forge a bond. Dante's endless
imagination goes into overdrive here, but the film is more gimmick
than anything else and ultimately feels a bit hollow. Fans of Short or
Quaid might like it more than most, though Dante's hardcore fans will
also appreciate seeing his stock players Dick Miller and Kevin
McCarthy. --Tom Keogh
