Tim Daly (Adventures of Superman) and his son Sam Daly (Justice League: The Flashpoint Paradox) have a regularly running Youtube series called The Daly Show… In the past to celebrate Sam getting the voice role of Superman they did an episode which included Brandon Routh (Superman Returns) and Dean Cain (Lois & Clark). Also they had an episode of Tim Daly (voice of Superman), Nathan Fillion (voice of Green Lantern), and Michael Rosenbaum (voice of Flash) play out their characters in real life, The Daly Superheroes.
With all the talk of Superman Vs. Batman the Daley team made them call upon Kevin Conroy (Batman) for a little fun. “The voices of Superman and Batman face off. Kevin Conroy, Tim Daly and Sam Daly, and it is written and directed by Ben Shelton.”
