Class Act: Morgan Spurlock, Joe Morley and Heather Winters -- the same group of filmmakers that exposed the greasy truth about fast-food "supersizing" -- team with director Sara Sackner for this eye-opening documentary that looks under the hood of America's public school curriculum. Under the microscope this time is arts education and its pitiable lack of funding, as well as the vital role a teacher can play in the lives of struggling students.
