VIDEO : Amber Heard and James Franco 'Have Great Chemistry'

James Franco and Amber Heard are at it again. Seven years after having appeared together in Pineapple Express, the two have reunited for The Adderall Diaries, a film adaptation of Stephen Elliott's best-selling memoir of the same name. The movie's director Pamela Romanowsky said Thursday at the Adderall premiere at the Tribeca Film Festival, ""James and Amber have great chemistry. As a director, it's really exciting to see two people who haven't spent much time together come into a room to do a scene and find this connection and electricity between them. It was really exciting to watch."??
