In the new film, 'The Walk,' Joseph Gordon-Levitt plays Philippe Petit, a high-wire artist who did what many said was impossible – walked a tightrope between the north and south towers of the World Trade Center.
Joseph Gordon-Levitt spoke with FOX 5’s Kevin McCarthy about the filming process. Gordon-Levitt said that a set was created of the top two floors of the World Trade Center and that it was surrounded by green-screens.
Gordon-Levitt said that he was trained by Petit, and did many walks himself, but that a double was also used for many scenes.
