Nemesis

In the original script Alex Rain was a 13 year old girl working undercover for the LAPD. Megan Ward, who had just worked with Albert Pyun on Arcade (1993), was considered and expressed interest, despite reservations over the high level of violence and a scene in which her character was fully nude (Ward was, obviously, a legal adult at the time). A few test scenes were shot before searching for financiers, which led Pyun to the Shah brothers at Imperial Entertainment. They agreed to bankroll the film on one condition: Alex had to be changed into an adult male and Olivier Gruner, their recent discovery, had to play him. Pyun agreed when the Shahs promised not to influence production in any other way. The concept of Alex being a woman was eventually used in the sequels, played by bodybuilder Sue Price.

When Alex steps out of the shower, we first see his butt, but in a later shot, he is suddenly wearing briefs.

The Japanese VHS features an alternate ending, containing an extended scene with Germaine, and a surprise appearance by Farnsworth at the very end, but also misses the entire stop-motion fight sequence on the plane, even though the sequence with an (inexplicably) badly injured Alex in Einstein's lab is intact.
