Michael Rosenbaum is pals with James Gunn, and with his legacy of playing Lex Luthor in Smallville and The Flash in Justice League and Justice League Unlimited, it seems like a missed opportunity not to have him in some role. Seeing him as a character in Creature Commandos or another animated series like Alan Tudyk could be fun, but I'd also love to see him get to play that same character in live-action. He could be fun as Ted Kord in a supporting role, with Jaime Reyes being the primary Blue Beetle in the DCU.
