Tilman has worked in TV for more than 25 years, including 14 years at the BBC. Although his main focus are stories that challenge traditional views of history, his films also cover contemporary stories and the future of the planet. One of Tilman's most important films, Earth Under Water, explores how humans can fight back against extreme sea level rise, predicted in the wake of global warming.
Tilman made his directorial debut in the multi-award winning documentary series The Nazis: A Warning from History, first broadcast in
1997. It is ranked 93rd in the list of the 100 Greatest British Television Programmes drawn up by the British Film Institute in 2000. Tilman went on to write and direct films for the BBC's flagship history
strand, Timewatch. In 2003, his lavish and action packed 'super-doc' Colosseum attracted 7 million viewers to BBC 1. The film was BAFTA and RTS nominated and
continues to be shown around the world, including Netflix.
Tilman left the BBC in 2004 and has been working as an independent filmmaker ever since. Recent hightlights include the award winning Legend of the Crystal Skulls, the investigative doc Inside the Gangster Code - The Grypsers with Grierson Award finalist presenter Lou Ferrante, and the award nominated mini series Bible Hunters presented by Jeff Rose. In 2015, the world premiere of Death on the Matterhorn about the tragic first ascent of the Alp's most challenging mountain got a massive 38 percent viewing share in Switzerland.
