Scarlett Johansson Explains How She Got Those Killer 'Lucy' Moves (Exclusive Clip)

The surprise summertime sleeper hit Lucy stars Scarlett Johansson as a woman transformed by a rare drug into an increasingly super-intelligent fighter. She not only shoots and kicks, but Lucy also learns to control computerized systems with her mind.

In this bonus Blu-ray/DVD clip, exclusively on Yahoo Movies, the 30-year-old actress explains how she developed both inner and outer strength to play such an extreme character convincingly in the sci-fi thriller.

Written and directed by Luc Besson (The Fifth Element, the Taken series), Lucy won praise for being flat-out fun. David Edelstein of New York Magazine wrote that the film is “an outlandishly entertaining mixture of high silliness and high style.” Andrew O’Hehir of Salon.com echoed the thought, writing, “Does it make sense? Not at all. Is it boring? Not that either.” Most hailed Johansson for her full commitment to the part.

Also starring Morgan Freeman, Lucy is now available on Blu-ray, DVD, and Digital HD.
