Jesse Eisenberg is the world's most dangerous stoner in an explosion-filled trailer for American Ultra.

Eisenberg and Kristen Stewart star as a marijuana-loving couple whose sleepy existence is upended when US government agents begin hunting them.

Long-haired hippy Mike Howell (Eisenberg) can't figure out why he suddenly has the know-how to expertly kill trained agents, but he puts those skills to use when he goes on the run with his girlfriend Phoebe Larson (Kristen Stewart).

Connie Britton and Topher Grace play the sinister government agents tracking Mike, while John Leguizamo is his over-the-top drug dealer Rose.

The Max Landis-written comedy is being brought to the big screen by Project X director Nima Nourizadeh.

Eisenberg and Stewart will reunite again this summer to shoot a new comedy from acclaimed filmmaker Woody Allen.

American Ultra opens on August 21 in the US and August 28 in the UK.
