The first time that the authentic voice of Jackie Chan was heard in a movie. All of Chan's prior Hong Kong movies had featured traditional dubbing of his voice for Cantonese and Mandarin releases. As a matter of fact, he wouldn't dub his own voice in a Hong Kong movie before Police Story 3 - Supercop (1992).
In his autobiography "I Am Jackie Chan: My Life in Action" (1998) there was one scene in the production in which director Robert Clouse was not interested in Jackie Chan's idea which was to flip out of the car. Clouse had wanted him to just walk from the car to his father's restaurant. Chan said: "No one will pay money to see Jackie Chan walk!". The reason he believes this movie failed was because he wasn't given a chance to choreograph the action scenes the way he wanted them.
First Hollywood movie of Asian actor Jackie Chan. ''Jackie's departure from his comic/bumpkin characters was his American film debut, 'The Big Brawl' (1980)'' according to a 2001 interview with Jackie Chan by Craig Reid published at 'Bright Lights Film Journal'.
According to his autobiography "I Am Jackie Chan: My Life in Action" (1998), both this film and Auf dem Highway ist die Hölle los (1981) were made while he was living in exile from Hong Kong due to a Triad-backed negotiation over his contract between Golden Harvest and his former employer Wei Lo.
