Got the (very nice) R2 disc of The Human Vapor a while back and burned a copy with English subs (courtesy of the old tokyomonsters.com site). Neat movie - like it a lot. There's a scene I swear James Cameron must've seen as a kid: the vapor man makes himself partially gaseous to move through some prison bars, very much like the T1000 in Terminator 2 (the scene in the mental hospital).
