The poor man's Indiana Jones, complete with Nazi subterfuge and heroine in distress. This paean to the cliffhangers of yore never really finds its footing, unfortunately. It's a rather tired story about a lost jet pack and the daredevil (Bill Campbell -- who hasn't had a starring role since) who finds it, and so on and so forth. Very straightforward, the mystery doesn't go very far and the love story (with Jennifer Connelly) is totally stillborn. The clever use of historical figures like Howard Hughes and W.C. Fields is really the film's only highlight.
