I hope you guys have the time to watch "The Dark Ages - An Age of Light". It's a different take on the often mistaken notion that "religion brought about the dark ages and pushed history back some centuries". It's more about how Christianity and Islam flourished in knowledge and science during the Dark Ages. And it has some serious study to back it up. I'm not aiming to change any minds. I just want open-mindedness from bigots out there.
Adkins is too short to for a Batman role but he'd make a good JPV Azrael IMO. Or Deathstroke. Cause he's a badass martial artist and I'd love to see Deathstroke do some of his action stunts like that in Undisputed or Ninja or Special Forces.
As for the topic at hand, I think Ben Barnes could make a good young Nightwing. Also that kid from Never Back Down. Forgot the name but he's got the youth and the build.
