"Brandon Lee was trained in Jeet Kune Do, Wing Chun, Muay Thai, and Shaolin Kung-Fu."
Of course, there are no sources backing up that statement. By any chance are there any articles that delves into Brandon's martial arts training?
Quick googling brought me these two links:
Bruce Lee began training Brandon in kung fu – more specifically, Jeet Kune Do – as soon as he could walk. Jeet Kune Do, or the Way of the Intercepting Fist as a style and philosophy is an amalgam of offensive, defensive and evasive manoeuvres derived from a plethora of different martial art forms, sports and literature. Following Bruce’s passing, Brandon continued training under Bruce’s senior students Dan Inosanto and Richard Bustillo. Elements of Boxing, Muay Thai, Shoot Wrestling, Filipino Martial Arts and Brazilian Jiu Jitsu are evident in Brandon’s style of choreography and fighting."
Still going throught this link but there appears to be a wealth of information in here: http://www.martialtalk.com/threads/what-level-of-skill-did-brandon-lee-have-in-the-martial-arts.74528/
