French filmmaker Luc Besson revealed that Scarlett Johansson's hard working attitude "seduced" him into casting her in 'Lucy.'
Besson told Sky News that he was so amazed by the 29-year-old beauty's knowledge about the film's theme, that he found her to be the perfect choice for the role, where she portrays a human with superhuman mental powers.
The 55-year-old old director added that 'The Avengers' stars may appear glamorous on-screen, but she had a really down-to-earth personality in real life.
