Joseph Gordon Levitt Debuts a French Accent for 'The Walk'

Movies are quickly vying for prime slots in the the fall festivals, and Robert Zemeckis' The Walk was just announced as the opening night premiere of the New York Film Festival in October. To be honest, I'm not sure why this movie exists. The Oscar winning Best Documentary of 2008 was Man on Wire, which gave us the actual account of the man who walked the rope between the Twin Towers- doesn't this all seem a bit redundant? If anything, it's a story that's probably more compelling in documentary narrative over fictional anyway, seeing how it's so procedural. What is this movie going to tell us that Man on Wire didn't? And what's the deal with JGL and weird, distracting makeup? Is that becoming his thing now?
