Man on Wire is a 2008 documentary film directed by James Marsh that chronicles Philippe Petit's 1974 high-wire walk between the Twin Towers of New York's World Trade Center. Based on Petit's 2002 book To Reach the Clouds, the film is structured like a heist movie, presenting archival footage, still photographs, re-enactments with actor Paul McGill, and contemporary interviews with participants including Barry Greenhouse, an insurance executive who helped facilitate the event.
