Just notice a trailer in Apple site: Kings of Pastry [1]

Filmmakers D A Pennebaker and Chris Hegedus secured exclusive access to shoot this epic, never-before-filmed test of France's finest artisans. The film follows chef Jacquy Pfeiffer, co-founder of Chicago's French Pastry School, as he journeys back to his childhood home of Alsace to practice for the contest. Two other finalists are profiled in the film -- chef Regis Lazard, who was competing for the second time (he dropped his sugar sculpture the first time), and chef Philippe Rigollot, from Maison Pic, France's only three-star restaurant owned by a woman.

I wish there will be a documentary for "King of Bread" :-)
