One of the more interesting facts in Greg Beeman's most recent blog entry about Heroes
is that the villainous character Christopher Eccleston was up for was the Sylar character. There had been some conjecture when Eccleston was originally rumored to be joining the Heroes
cast that he was playing Sylar
. And Eccleston had mentioned that he wasn't really interested in playing a villain on American television.
I think it definitely worked out for the best this way -- I think Eccleston works really well in the role that he's playing, and Zach Quinto is very very creepy as Sylar.
