The Adderall Diaries stars James Franco as a prescription drug-addicted novelist paralyzed by writer’s block who becomes obsessed with a murder case and involved with a reporter, played by Amber Heard. Directed by Pamela Romanowsky, and based on Stephen Elliott’s autobiographical 2009 crime thriller of the same name, the film also features Christian Slater as the man suspected of the homicide and the great Ed Harris as the vindictive father of Franco’s character.

The Adderall Diaries, which is out in theaters and on VOD on April 15, is available to watch now exclusively on DirecTV. You can see a clip from the film, above.
