Attached are some pictures from the 1979 CBS Captain America movies. Since Space:1970 has started covering TV superheroes of the era, I figured you might want these.
Me again: I don't think I actually saw the two Captain America TV movies when they originally aired, although I did eventually pick up a VHS copy of Captain America II: Death Too Soon in the 90s, and I own the double feature DVD now. But I do remember that my friends who had seen them were very upset about the costume changes and revamped origin story. When I watched the two telefilms on DVD a while back, I personally found it difficult to get too worked up about either change (although the costume in the first movie was really bad!).
Yeah, they're silly movies and deviate substantially from Marvel Comics lore and legend, but they're entertainingly silly, and that's enough for me.
