So is Saoirse confirmed as Melanie? She doesn't fit the physical description and she seems a bit too young for Mel. However, I thought Kristen was a crappy Bella (I know that's not a popular opinion around here & I'm sure I'll get flamed for it). I've never seen Saoirse in anything so I'll give her the benefit of the doubt. I imagined Melanie as a Latina. I could see Hayden Panettiere as Pet/Wanda after she gets 'moved.' It's probably too small of a role for her though but it would open her up to be in a sequel if Stephenie finally cranks it out.
