Yes, we once again throw Matt Bomer's name into the ring. But can you blame us? Bomer was a frontrunner for Superman before Henry Cavill landed the coveted role, and his clean-cut good looks made him a fit for the billionaire playboy Bruce Wayne as well. But his shorter height (5'11") and stature when compared to Cavill was hard to overlook.
But as Dick Grayson - using acrobatics and speed over brute strength - Bomer seems to possess the physicality needed (Magic Mike proved he's in top shape), while still possessing the looks expected of Bruce Wayne's second-in-command. And lest we forget: he had the good sense to take himself out of the running for Fifty Shades of Grey.
Bomer has proven his versatility and screen presence starring in Chuck and White Collar, so his age is the only real question mark. If it isn't, then consider Bomer and Vampire Diaries' Ian Somerhalder in a dead heat.
