Nestor Carbonell - I don't know what it is about this guy. He's just...cool.
I used to just know him as that guy who was on Suddenly Susan(yes, I actually watched that show). Never did I think I would see him in so many other things this much later!
As for the eyeliner, you should watch the video of him from the LOST panel at Comic-Con last year. F'ing hilarious!
We'd better learn Richard's backstory this season...
I find it pleasently ironic that the same man who played Batmauel in the short-lived live-action version of THE TICK would go on to appear in THE DARK KNIGHT. Did you think that it looked like he wore eyeliner in TDK?
