Justin Webster, Director, Writer and Executive Producer

Crafting non-fiction narratives became Justin’s passion when he worked as a newspaper reporter, after studying classical literature. Working with photographers as a freelance writer led to directing his first short documentaries. In 2004 his first feature documentary, a vérité film about a year inside FC Barcelona, won several international awards. His films and series are either investigative, constructed through testimonies, archive and recreations, or vérité style following an unfolding story in the present. Justin believes non-fiction, told with craft but without invention, can be as dramatic and creative as the best fiction – and often more revealing.
