Natalie Portman does not look like she's 40! She's only 28, you crazy! If you ever saw the televised version of Pride and Prejudice with Colin Firth, I think she'd be an excellent Zombie Slayer version Eliza. In fact, I believe she's who I pictured whilst reading the story. But you are right one thing, Natalie Portman is far to tan to be Eliza. She isn't a perfect fit, but I still think she'll do well.
