A great documentary on Rolls Gracie.
Rolls Gracie was one of the most important members of the Gracie family, being the family’s champion in the 1970’s, considered to be the father of modern day jiu jitsu through his ideas on cross training in different martial arts. Rolls is arguably the most influential figure in the history of the sport, having affected most of the following generations in jiu jitsu, including great practitioners such as “Carlinhos” Gracie (founder of Gracie-Barra), Rickson Gracie (BJJ legend), Royce Gracie (UFC Hall of Fame), Romero Cavalcanti (Founder of Alliance BJJ team) and many others.
