My first 'Imagine' made back in 2009, and pretty much my first grown-up documentary as director.
The BBC had bought a 26 minute film about William Eggleston by the brilliant German director Reiner Holzemer, and wanted me to expand it into a longer film. Reiner kindly let me pick his film apart, and then stitch the footage back together in my own way - with added interviews, new footage I shot myself, and a completely new soundtrack. But really the whole thing depends on the incredible footage he shot of Eggleston working in Memphis.
Editing Reiner's rushes taught me two valuable lessons about how to interview someone who doesn't talk much: 1) think hard before you ask a question and 2) don't fill the silence!
