The RockCaptain Marvel may be charged with protecting mankind, but that's nothing compared to being charged with finding the right actor to fill his heroic tights.

"It's up to the fans," he told me repeatedly when I interviewed him this past Saturday.

So we're opening up the floor to you. Do you think he's right for either role, and if so, which one? It's all yours to decide. But, remember, to borrow a turn of phrase from another superhero, "With great power comes great responsibility."
