Only one person should play Lex Luthor on Supergirl; Michael Rosenbaum. Get this done DC-CW
then you’re probably going to be out…
Haha, that would be a nice tie-in, but probably not gonna happen.
He has a good relationship with James Gunn. Since they’re talking about recasting anyway let him be Lex in Suicide Squad. I don’t think he’d shave his head for a full tv series anymore again.
