'Twilight Eclipse': Taylor Lautner teaches Wolfpack 101

"The Twilight Saga: Eclipse" has a bigger cast than the previous films considering there's a newborn vampire army to handle.

In particular, we delve more into Jacob's ( Taylor Lautner) wolfpack and get to know them better.

Luckily, in a recent "Access Hollywood" clip, Lautner gives this handy rundown of who's who in the pack hierarchy, which is good if you can't keep them straight. Not saying that all shirtless wolfpack members look alike, but you might be a bit distracted when looking at them.
