The Hollywood Reporter reports Uma Thurman has joined American Ultra, an action-comedy from Project X director Nima Nourizadeh. The film stars Jesse Eisenberg and Kristen Stewart, as a stoner and his girlfriend who are put in danger when Eisenberg’s character becomes the target of a government operation. Thurman will play the woman in charge of a secret government program to create sleeper agents, who comes to defend her babies, when others within the government threaten to kill them. If she brings the ferocity she seemingly brings in that Nymphomaniac clip, those sleeper cells are probably chill.
