1. Malin Akerman
Who? Swedish-Canadian actress/model/singer. Last seen wearing lurid latex and hitting people in slow-motion in Zack Snyder's Watchmen.
Why? Because she has the required air of Nordic chill (is she cool but kind or cruel and icy?) and because she needs to be saved from having her edginess dulled in rubbish rom-coms like the upcoming Couples Retreat with Vince frickin' Vaughn.
