4. Joe Manganiello
Age: 36 Allegedly one of Snyders possibilities for Superman prior to Cavill being cast, Manganiello had scheduling issues due to his True Blood gig. Playing the werewolf Alcide Herveaux on Blood gives Manganiello some dark-edged pulp credibility and hes no stranger to comic-book universes, having played Flash Thompson in the original Spiderman trilogy. The real question here is the same as Gosling, can Manganiello step into the character to the degree needed here? Some of this depends on exactly how the script imagines Batman, but right now Manganiello seems better suited as Bruce Wayne than as his alter-ego. The upside of casting him is that much like Bale in Batman Begins, the franchise will have a recognizable face that, at the same time, isnt an overexposed star.
