Quinto on Heroes
I began watching Heroes after I heard about Zach Quinto being cast as Spock. I've been very impressed with his character on Heroes. He handles the duel nature of Sylar/Gabriel Grey very well. Which is good because of all the cast members, he has the most difficult job. Spock is by far the most explored character in Star Trek so for Quinto to bring something new to the screen would be quite impressive.
Plus, he's a very handsome fellow. Maybe he'll be the one who'll get his shirt ripped off all the time in the movies.
