In his newest film, just before he makes his cinematic turn as Lex Luthor in next year's Batman V Superman: Dawn Of Justice, Jesse Eisenberg plays low-level stoner turned Jason Bourne-style killer Mike Howell in American Ultra.

In the comedic thriller, Howell is an accidentally activated government sleeper agent, but his role no longer plays into their plans. Also starring Kristen Stewart as his girlfriend Phoebe (the second movie the two have appeared in together after 2009's Adventureland) and Topher Grace as the film's antagonist Adrian Yates, Howell must find a way to thwart the government's efforts to take him out and save his girlfriend at the same time.

Check out the official red band trailer for American Ultra below, which is set for release August 21st.
