Now Werner Herzog is promising to teach budding directors the art of guerrilla film-making online for the small matter of $90 (£61).
Herzog, who famously stole his first camera from the Munich film school, claims in a video for the Werner Herzog Film-making Masterclass that his students can learn the essentials of the art in two weeks.
In 2009 Herzog opened his Rogue Film School in Los Angeles, featuring a course taking place over a single weekend.
He berates wannabe directors who shoot hundreds of hours of footage for later editing, warning them that film-makers “are not garbage collectors”.
