For anyone that got to see Alfonso Cuaron's Gravity in the theater, it's a breathless, palm-sweating, white-knuckled experience that is hard to describe. Essentially Castaway in space, Sandra Bullock is by herself for most of a tight 90-minute adrenaline rush, just trying to survive. In this episode of CineFix Top 100, Clint, Cal, and Alex celebrate this harrowing film's 10th Anniversary, with its Academy Award winning Visual Effects Supervisor, Tim Webber. Tim walks us through all the little details, and tries to describe how necessity really is the mother of invention when making a movie where only the faces are real. Buckle up.
