Scar Jo's work ethic seduced me, says 'Lucy' director Luc Besson

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.
