Guillaume worked on paragliding videos (Redbull Vertigo, Ozone Paragliding, RedBlues, etc) before moving to mountain sports and climbing films. In 2002, while working with the production company 7DOC, he directed the film, "Flying Babouches" which received prizes at several film festivals. Since he started working for Petzl in 2001, Guillaume has directed nearly all the Petzl videos, including "Navalameca70's" (2006), "Outdoorgames" (2008), "Roctrip Millau" (2003-2009) and "Azazel" (2007). With his artistic background and his keen interest in paragliding and climbing, Guillaume brings a unique graphic and esthetic sensibility to his climbing films.
