In this August 7, 1974, file photo, Philippe Petit, a French high wire artist, walks across a tightrope suspended between the World Trade Center's Twin Towers in New York. Petit and his companions surreptitiously strung a wire between New York City's recently constructed World Trade Towers on Aug. 6, 1974, and Petit walked across it the next day. He danced, strutted and clowned around for 45 minutes as startled bystanders watched from 110 stories below. The Frenchman's stunt is the subject of the 2008 documentary "Man on Wire" and the 2015 film “The Walk”, starring Joseph Gordon-Levitt.
