00:00Did you know that in The Incredible Hulk, the breathing technique used by Edward Norton to control the Hulk's rage actually exists in real life?
00:06The breathing and self-control master who appears at the beginning of the film is played by Rickson Gracie, a true Brazilian jiu-jitsu master.
00:12He is well known for teaching deep diaphragmatic breathing and chi-control.
00:15Norton trained with him personally to prepare for the role.
00:17I really like how this version of Banner went on a spiritual journey to control his emotions and restrain himself from transforming into the Hulk.
