Well, she certainly looks the part better than Ms. Biel, who was previously rumored for the role.

Well that's excellent news for Jaimie!! I was wondering why she had to change her Twitter name and this thread answered my question.

Congratulations on the role Jaimie!

Awesome news.

The cast & crew are really looking good for Thor - I have very high expectations.

I'm not very familiar with her, having only seen her in a guest appearance on Bones, but I think she looks great for the role. She definitely looks like Sif. And if Branagh cast her, then she must be a great actress. Seriously, Branagh's like the gold standard, so I think I'm gonna check out her previous work.

Just glad to see Sif cast, though. She's one of my favorite characters in the Thor mythos (or the Marvel Universe, period), so I'm really looking forward to seeing her in the movie.

She's just perfect for Sif.

She's going to be a great Sif - perfect combo of toughness and beauty.
