Behind the camera: How BP and Psona got a Paralympic sprinter to outrun a train

BP's new film to promote its partnership for this summer's Paralympic Games features a German sprinter who carved out a second life as an athlete following a tragic accident.

David Behre, who will participate in this year’s games in Rio de Janeiro, stars in BP’s "Running man" ad, created and produced by Psona Films.

The film showcases Behre’s personal and moving story, as well as using CGI to make it appear as if he is outrunning a train. In 2007 he lost both legs after being hit hit by train while on a bicycle.

The ad’s launch marks 100 days to go until the start of the Paralympic Games and is the third instalment in the energy company's "The energy within" campaign featuring athletes, which began last year.

Campaign went behind the scenes and spoke to Mark Rose, the brand communications manager for BP; Katy Eyre, the managing director for Psona Films; Stirling Archibald, the visual effects supervisor at post-production agency Unit Media; and Stewart Sugg, the film’s writer and director.
