Here's the first crossover between the DC-CW characters and the big screen.. or is that Batman's first appearance on the DCW Universe? Well, anyways this is a funny little promo that ran during Supergirl this week, a cross-promotion with the upcoming Lego Batman Movie. Check it out, it's great!
Aw! They should totally have the CW actors voice these characters more often from now on. Sounds like they couldn't get Brandon Routh for this, though. Since The Atom's just.. "there".
