This is apparently the guy who's going to play Aquaman during the fifth season of Smallville.
Kristin at E! Online has revealed the news we've been trying to figure out for a while - the role of Young Arthur "A.C." Curry, aka Aquaman, has been cast for the episode "Aqua." The actor playing him is a newcomer named Alan Ritchson
And some hints from Gough on the behavior of young Arthur Curry in "Aqua:" "He is determined to save the oceans and Lex is doing something nefarious involving a defense contract. In a weird way, Arthur is probably two feet from being an eco-terrorist and Clark has to sort of real him back in terms of what he's willing to do."
Also, James Marsters, Spike from Buffy the Vampire Slayer, is playing Brainiac, the big bad, for this season on Smallville...
...And about James Marsters' role as Milton Fine, aka Brainiac: "We know that there was basically going to be something big in that ship," Al Gough told CFQ's Ed Gross. "The ship opens and Kryptonians come out, but they aren't the major ongoing threat. Brainiac comes out of the ship and takes human form, like in Terminator 2, and he's a being of artificial intelligence. He basically takes the guise of Dr. Milton Fine, a college professor who ends up teaching Clark. We call this the grand seduction of Clark Kent, where Brainiac is trying to turn Clark against humanity in general, and Lex Luthor in particular. He basically wants Clark to see that Krypton was better than Earth and that, basically, he's got the making here for a new society. Unlike Jor-El, whose intentions become clear in the season opener, Brainiac has a much more nefarious plan and he uses Lex in it."
...James Marsters is looking forward to his character's psychological seduction of Clark. "I don't have to beat Clark at all," he offers. "It's very important I talk him into joining me. It's always a more interesting thing to watch. Frankly, there's a lot of ammunition on my side. Earth is a beautiful gem of a palnet and there aren't a lot like it around. But there's just one problem: human beings, who are ruining both the atmosphere and the topsoil at an alarming rate and there's no way we're going to be here in 10,000 years. There's nothing in human history that suggests the bare hint that we are about to make the moral leap into behaving the way the philosophers have been asking us to over the years. So the best thing to do, both for Kryptonians and Earth as far as Brainiac is concerned, is to eradicate these stupid, barbaric failures of evolution. His feeling is to just get rid of these humans and let's have a new Krypton, and he wants to use Clark as a tool to achieve his goals."
Why yes, I AM a huge geek, thanks. But I'm okay with that.
