SCARLETT BYRNE – FALLING SKIES, HARRY POTTER MOVIES
She sported a Malfoy-colored wig in Falling Skies, and we think she’d look awesome with a darker hair color than her natural one. She can actually look really serious without that much effort, something she probably perfected in the Harry Potter movies, but she also has a warm look when she smiles. Although she’s on the short side, we think she could still make it work.
ISABELLE FURHMAN – THE HUNGER GAMES, ORPHAN
At 18, Isabelle Fuhrman is at the younger end of the scale, but she’s been in the acting game longer than most people on this list. She got in plenty of fight training as Clove in THE HUNGER GAMES and creeped us out in ORPHAN, so we know she can play off Isabelle’s hell on wheels attitude. But she comes across so bubbly in interviews that we’d love to see her take on the softer side hidden underneath as well!
