Scarlett Johansson Reaches Full Potential in 'Lucy' Trailer

Scarlett Johansson will continue to kick ass on the big screen in Luc Besson's Lucy, which finds the title character transforming from drug mule into superhuman because of her unusual cargo. As the drug leaks into her system, Lucy gains more and more abilities by using uncharted parts of her brain.

Earlier this week, we got our first official look at the character. Morgan Freeman also stars in the picture as a scientist researching the full potential of the brain. Lucy debuts on Aug. 8.

Johansson stars in not one, but two films hitting theaters this weekend: She returns as Black Widow in Captain America: The Winter Solider, and preys on humanity in Under the Skin.
