Is this the new show that has that guy from "Lost"?
Yes. The character that built themachine was on Lost. And yes there are two characters on H-50 also from Lost.
Yes, the guy who played Ben Linus on Lost is now in Person of Interest. And Jim Caviezel? I'll have to check that one out.
Looks like Hawaii 5-0 has Jin from Lost, Boomer from Battlestar Galactica, and Hiro from Heroes.
Nice to see that these actors who developed these well-liked characters are finding life beyond their initial hit series.
