If you thought Blackbeard intimidating in the trailers for Assassin's Creed IV: Black Flag, wait until you see actor Mark Bonnar doing his voice. I peed a little.
I spied Bonnar once before in a two-part episode of Doctor Who (2011's "The Almost People" and "The Rebel Flesh"), and he didn't strike me as particularly scary. Seeing him open his mouth and that gruff roar come charging out — now I am terrified. He's what every angry father hopes he sounds like when he's shouting.
The other two, Matt Ryan (Edward Kenway) and Ralph Ineson (Charles Vane) give their characters a good turn, and they are all sporting pirate-y beards, but I'm in it for Bonnar now.
