She has played the sweet innocent young girl before in one of her more recent movies and she is obviously capable of bieng an absolute badass on screen (and irl). This is confirmed after watching Westworld where her character is essentially a Disney character turned Terminator. The only problem imo is that her jawline is a little too masculine for Elizabeth, since Liz has very skinny facial features especially in her7ec cheeks. But other than that I'd love to see Evan take on the role if they ever decide to make a film. I already have ideas on who could play Booker too.

I'm not saying she is old, but Elizabeth is 19. Rachael would be in her 30s if this ever happened.

Dude, she's only 29 and still looks incredibly young, she would pull it off easily.

Maybe a little to tall and old now. However she would've been a great fit.
