Reason #1: Age
Rumor has it that DC is on the prowl for an older actor to don the cape and cowl this time around. Born in 1970, Coster-Waldau has a full decade on the hipster choice for the role, Ryan Gosling, and is just two years younger than the other potential canidate for the role, Josh Brolin. This means that he fits perfectly into the age bracket that the gossip vine has established for the part.
Reason #2: Relatively Unknown to American Audiences
Coster-Waldau has a slew of European movies and minor American film appearances to his name, but outside of his roles in "Mama" and "Game of Thrones", he's a relative unknown to mainstream audiences. Zack Snyder went with a relatively unknown actor when he cast Henry Cavill as the Man of Steel, so there is a fairly good chance that he might do so again this time around.
Reason #3: Stunt Experience
If you're unfamiliar with "Game of Thrones", Coster-Waldau's character on it doesn't just lay around on the couch all day being fanned by half-naked women. The role of the Caped Crusader is very demanding physically, so his work on GoT would be a huge asset.
Reason #4: He Can Wear a Suit
... Need I say more? While many fans mock Bale's Batman, there is no denying that Bale played the part of a billionaire playboy perfectly. Whether he's clean-shaven or a little scruffy, Coster-Waldau certainly seems to have the looks and the charm to fill Bale's shoes in this capacity.
Reason #5: Jawline
When you're going to be spending a great deal of your screen time with only half of your face showing, a good jawline is vital. Thankfully, Coster-Waldau has one that you could cut glass with.
Reason #6: Intelligent
Coster-Waldau has already played a detective once on the short-lived FOX series "New Amsterdam" and his character on GoT, Jaime Lannister, isn't exactly a slouch when he comes to putting the pieces together either. A master-tactician is what I'm personally dying to see on film this time around, and Coster-Waldau has already proven that he can play one.
