The film quality of the Clouse-directed footage is noticeably higher than that of Lee's earlier Hong Kong films, and John Barry provided an original soundtrack. The film also featured performances by experienced actors as well as up-and-coming stars, including two recipients of the Academy Award for Best Supporting Actor (Dean Jagger and Gig Young) and several who have been honored with a star on the Hollywood Walk of Fame, including Bruce Lee, Dean Jagger, Chuck Norris, Hugh O'Brian, and Gig Young (in his final film).
