The German distributor also held the rights to
Jackie Chan's directing debut
The Fearless Hyena (1979) (aka "Fearless Hyena"). That film was released with ca. 20 minutes cut. To gain a higher box office for this film, it was cut down to ca. 45 minutes and then the 20 minutes of deleted scenes from "Fearless Hyena" were inserted into it (basically creating a completely different film).
