Kristen Stewart Stars in Final 'American Ultra' Trailer With Jesse Eisenberg - Watch Now!

Check out Kristen Stewart being totally badass in this final trailer and poster for her upcoming movie American Ultra!

The film is a fast-paced action comedy about Mike (Jesse Eisenberg), a seemingly hapless and unmotivated stoner whose small-town life with his live-in girlfriend, Phoebe (Stewart), is suddenly turned upside down.

Unbeknownst to him, Mike is actually a highly trained, lethal sleeper agent. In the blink of an eye, as his secret past comes back to haunt him, Mike is thrust into the middle of a deadly government operation and is forced to summon his inner action-hero in order to survive.

American Ultra also stars Connie Britton and Topher Grace. It hits theaters on August 21!
