Olivier takes his name from his birthday: the 6th of August 1965 is the 20th anniversary of the dropping of the Hiroshima A-bomb. He grew up in a Paris banlieue, and after qualifying for a diploma in psychology, was active as an artist, including graffiti. After meeting Jean-Baptiste Mondino in the 1990’s, he started working in films. Following Mondino's advice, Megaton wrote the screenplay of his first short film No Way, or Le Coeur du Phoenix, which received funding from the CNC. Completed in 1991, the film went on to win several prizes at film festivals. Fourteen other shorts were to follow. At the same time, he made documentaries for the Georges Pompidou Center and another one for the ARTE TV. His first novel Le Facteur humain (The Human Factor) was also published in 1998. Exit, shot in 1999, is his first feature. He then completed his adaptation of Maurice Dantec's novel The Red Siren in 2002. In 2007, he directed the Second Unit of Hitman with Timothy Olyphant. In 2008, he directed Transporter 3 for producer Luc Besson. Megaton has also directed more than eighty music videos and commercials.
