Heheh, glad you're all enjoying the footage of Nuclear Man 1 - it really is incredible. Definitely a good call about him being the closest thing to Bizarro we've seen so far in a Superman movie too.
Here's something weird I noticed from the most recent DVD release of Superman IV. Check out Nuclear Man on the cover!
Call me crazy, but that does NOT look like the same guy who played him in the movie. I'm pretty sure that's a shot of Gene Hackman from another film since the hair is fairly different too, but Nuclear Man's face looks very different in the movie compared to the one seen on the cover.
