I have never really seen much at all of Nestor Carbonell. So i'm just going to stick to Lost. I think i remember him being introduced in season 3 as a great character and has been since! Most of the new characters got their flash backs such as Linus, Farady, Miles, Charlotte, Juliet etc.
He plays a man who doesn't age and was finally explained why he never ages and i think he's now 140 years old! Non the less he's shown how under rated many tv actors are and i really hope that he does get a role after lost because he definitely deserves one.
I really like Nestor and his work. He was great on Suddenly Susan and LOST. Both were and are great roles for Nestor. I really enjoyed seeing the dark side of him in "Smokin Aces". He was really creepy and scary in that, but I enjoyed it! It was so weird to see him kill Matthew Fox's character! Anyway, i love this guy and rate him 10 out of 10! :D
