The original cut of the movie was so poorly received by audiences that the film had to be extensively re-edited in a desperate attempt to please fans by removing many scenes of Billy Magnussen and focusing more on Philip Ng as Bruce Lee.

Martial artist, actor, and stuntman Mike Moh campaigned for the role of Bruce Lee in the film.

The character of Steve McKee was based on actor Steve McQueen who studied with Bruce Lee in the late 1960s.

Philip shot to fame after starring in Kung Fu TVB drama "A Fist Within Four Walls" with his role as Lung Sing Fu.
