In the late 70s, a toku series was created based on Spider-Man...not really much to do with the comics, but it's still incredibly bizarre, corny and funny. I love it, but then again, I'm a huge Sentai/Power Rangers fan. It has the huge fighting robo and everything.
Note - it's Japanese but has English subs. If you have half an hour to spare, it's worth checking out.
My son's birthday was this weekend, and this (and Juno) was what he wanted to see. There was some really cool CGI with sabertooth tigers, mammoths, and some Jurassic Park looking huge killer ostriches.
