Query: Superman + Captain Marvel best team up

Superman/Shazam the return of Black Adam is the best short from the DC universe original movies. Too bad they never released the trailer but trust me it is worth it in a sense if you are a Superman fan or Captain Marvel fan. Not only watch the extras Green Arrow, The Spectre and Jonah Hex but also included the episodes which feature these heroes Justice League Unlimited "Clash"with Captain Marvel, Batman the Animated series with Jonah Hex, Justice League Unlimited "Initiation" with Green Arrow and Batman: The brave and the bold "Chill of the night" with The Spectre.
