A documentary maker following the Black Keys on tour says the band's upcoming movie will focus on the relationship between band members Dan Auerbach and Patrick Carney.
Noah Abrams told Spin.com the pair's relationship would be at the heart of the film, which he hopes to finish shooting in August and release next year.
"A lot of music documentaries spend too much time trying to make people look cool," Abrams said.
"I'm fortunate enough to know both these guys pretty well and their relationship is pretty incredible and very funny."
Abrams said the film would chart the band's success from badly attended early tours to one of the world's biggest rock acts - and would include "perhaps the greatest soundtrack of all time".
