Does anyone else remember this? I remember thinking that it was really cool when I was a kid. It was shown as two TV movies in 1979. From imdb.com -
'The adventures of many of DC Comics greatest superheroes and villians. In the first episode, The Challenge, the superheroes must race against time to stop the diabolical supervillians' plot to destroy the world.
