Among the martial arts Bob Wall has studied Okinawa-te karate under Gordon Doversola.
In 1968, Lewis sold his share of the studio to Chuck Norris. He is featured in a number of films, most notably three appearances with martial arts master Bruce Lee. He appeared in the 1972 film Way of the Dragon with Bruce Lee, along with Chuck Norris.
He then had a major role in Bruce Lee"s most famous film (in the western world) as O"hara in Enter the Dragon in 1973.
He later appeared in Game of Death, Bruce Lee"s incomplete film re-cut in 1978, and played small roles in Chuck Norris films, such as Code of Silence (1985), Firewalker (1986) and Hero and the Terror (1988). More recently, in 2009, Wall starred as a bodyguard in the film Blood and Bone.
While portraying the dreaded O"Hara, an urban legend surrounding the making of Enter The Dragon claims that he never quite got along with Bruce Lee and that the fight on the parade ground where he smashed the bottles was more than just a managed fight. However, Wall and others present at the time deny this story, stating the tale was blown out of proportion and that Wall and Lee were actually good friends.
Wall has studied several arts under many notable masters.
They include Judo under "Judo" Gene LeBell, Okinawan Shorin-Ryu under Joe Lewis, and Brazilian Jiu-Jitsu under the Machado Brothers. 75-2280, the first book of its kind for martial artists.
