Joss is a fan of petite brunettes, and of his roster of small ladies with luscious locks, Amy Acker is our runaway favorite. This girl can do no wrong. From ancient demon trapped in a human body to Shakespearean romantic lead, Amy has shown a huge range while working with Joss. We'd love to see her tackle another challenging role on S.H.I.E.L.D. — maybe a former baddie struggling for redemption as part of the team? She would rock that.
