On the Zap 2 It website, there is an article and a video interview with Alan Ritchson, who reprises his role as Arthur Curry/Aquaman in the season's ninth episode, "Patriot".
One quote of interest in the interview with Ritchson mentions his new super-hero suit, which is much different than the orange-and-green Aquaman suit he's worn in the past:
"Die-hard fans know that Ritchson, as Aquaman, was recently photographed in some new clothes... specifically, a black wetsuit, which replaced the traditional orange and green one. Let's just say orange isn't Ritchson's color. "When I walked in and saw the orange and green on my rack, I threw up and I left," he jokes. The suit is a symbol of his new attitude. "That's it, man. He's going stealth. He's grown up.""
There's much more from Ritchson on his guest stint on "Smallville", but you'll have to go to the Zap 2 It website to check it out. Also, be warned of episode spoilers.
