Very good point, talldede. Although I'm still disliking the fake-Indian thing, I do agree that Taylor suits the friend-with-a-crush role. I remain skeptical about his ability to really pull off the werewolf-with-attitude, and portray the bitterness and anger that Jacob experiences throughout much of the series.
The movies will have to be made close together so that the actors don't age too quickly (which was very well-done by the makers of the Harry Potter series, but of course those actors were supposed to age over a period of years while the Twilight saga is set in a very short time frame). I don't know if he'll have the chance to mature enough to be believable.
