About a month ago, we reported that Joseph Gordon-Levitt was circling a lead in Robert Zemeckis' high-wire act, To Reach the Clouds.  Now, it looks as if JGL has indeed committed to playing the role of French tightrope walker and high-wire artist, Philippe Petit.  The film's working title is shared with Petit's memoir, which was adapted by Zemeckis and Christopher Browne.  The film will build to a third-act climax which recreates Petit's "artistic crime of the century" in which he and his co-conspirators snuck to the top of the World Trade Center in 1974 in order to make his famous attempt at crossing between the two towers.  In addition to the thrilling caper aspects of the plot, Zemeckis is planning to shoot the movie as a 3D spectacle in the vein of Avatar, Life of Pi and Gravity.  Production is scheduled to start this May.  (Via Deadline)
