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.
I don't know what the Game Plan is, but if The ROck just started shooting it then it's not the same thing as Gridiron Gang. Gridiron Gang is already completed, the trailers is already on the internet and set to be released in September.
