Director on 'The Sparks Brothers' documentary: It's like watching two people push a boulder uphill

"It's maybe not as dramatic as an addiction story or a fallout or a premature death, all of the things that are in other music documentaries, a fallout and a reunion. The thing with them is to exist in the business for 50 years through changing times. It's like watching two people push a boulder uphill" - director Edgar Wright says in The New Cue interview about The Sparks Brothers. "It's one of the rare music documentaries about brothers in rock where the brothers don't fall out".
