Scarlett Johansson looks set to star in Luc Besson's new action thriller.
The Hollywood actress is in final negotiations about the part in Lucy, according to The Hollywood Reporter's Heat Vision blog.
The film follows a woman who is forced to be a drug mule. Things take an unexpected turn when the drug gets into her system and turns her into "an a**-kicker". She finds she has developed incredible physical abilities, such as an inability to feel pain.
French filmmaker Luc wrote the movie and will also direct.
Scarlett, 26, is no stranger to action, having played the Black Widow in the Avengers Assemble movie and Iron Man 2. She is also set to reprise the role in Captain America: The Winter Soldier.
