Did You Know?


The scenes of crewmembers swimming outside the sub were shot on dry soundstages with the actors suspended from wires. There was some additional hazard involved because, to avoid reflections from the metal, the wires were washed in acid to roughen them, which made them more likely to break. To create the impression of swimming in a resisting medium, the scenes were shot at 50% greater speed than normal, then played back at normal speed. See more »

Capt. Bill Owens: Mr Grant, send a message telling them that the Proteus is ready.
Grant: The Proteus, what's that?
Capt. Bill Owens: That's the name of this vessel; sounds better than calling it the U91O35.

A Great Thriller
21 July 2003 | by (Los Angeles, California) – See all my reviews

This is not only a great science fiction film, it is also a great thriller as well. I especially loved the fact that this was supposedly done in "real time" and that the characters and that it was not only a mission to save the scientist life, but a race against time before the miniaturization wore off. Also, even though the effects are dated, they still were pretty good for the era they were produced in.
