Scarlett Johansson’s year at the movies has been inhuman. First, she played a sentient computer program in “Her,” then a predatory alien seductress in “Under the Skin.” Now, in Luc Besson’s “Lucy,” she’s a woman who becomes superhuman when an experimental drug unlocks 100 percent of her brain power. The days of playing zookeepers in “We Bought a Zoo” seem long behind her.
