The film chronicles Philippe Petit's 1974 high-wire walk between the Twin Towers of New York's World Trade Center.

The film is crafted like a heist film, presenting rare footage of the preparations for the event and still photographs of the walk, alongside re-enactments (with Paul McGill as the young Petit) and present-day interviews with the participants, including Barry Greenhouse, an insurance executive who served as the inside man.

In an interview conducted during the run of Man on Wire at the 2008 Tribeca Film Festival, director James Marsh explained that he was drawn to the story, in part, because it immediately struck him as "a heist movie", though, as Jean François, one of Petit's collaborators, said, "It may have been illegal...but it wasn't wicked or mean.

"[9] The film opened theatrically in the United States on 29 August 2008, earning $51,392 its first weekend and ranking 37th at the domestic box office.
