Scarlett Johansson will kick major butt in theatres across the world on Friday, as Natasha Romanoff in Captain America: The Winter Soldier. That same day, in select cities, audiences can also see one of the actresses' more daring performances, as a seductive alien in the film festival favourite Under the Skin. But, for those hoping to mix some of the former film's brawn with the latter's brain, there is hope, as Johansson will be playing an omnipotent girl looking for revenge in the thriller Lucy, from La Femme Nikita director Luc Besson.
