scarlett johansson lucyScarlett Johansson knows exactly how to escape from captivity: Opening her legs.

In this violent, NSFW clip from Luc Besson's "Lucy," Johansson shows off just how much of a badass she is. First, she gets out of her cell by coyly spreading her legs for one of her guards. After laying him out flat, she takes his gun to confront her other captors. Let's just say: It does not go well for them. At all.

As the titular character, Johansson is a genetically-modified assassin who is able to use more than 10 percent of her brain (unlike the rest of us un-evolved apes). Think of it as a "Nikita" for this generation.

"Lucy" hits theaters on July 25.
