Legend
It had been a while but Cap had a made for TV movie, back in the late '70s. There were also the cartoons of the mid-'60s. Sadly, Thor only had "Adventures in Babysitting", since the mid-'60s cartoons.Cap and Thor had had no exposure to speak of outside of print comics at that point. If you weren't reading comics, they weren't a big deal yet in the broader movie market.
