While filming the stunt where he leaps from a wall onto a tree, the branch Jackie Chan grabbed a hold of broke and he hit his head on a rock, nearly killing him and leaving him with a permanent thimble-sized hole on the right side of his head. The fall also left him hard of hearing in one ear.
Jackie Chan's hair grows between shots (see goofs). This is because before he made this movie, his hair was always long, but he cut it for this movie. However, after his accident, when he fell from a tree onto rocks nearly killing himself, he considered having long hair to be lucky and grew it again.
The car driven by Jackie Chan is a Mitsubishi Colt Targa Concept, which is a two-door, two-seater version of the Colt with its roof chopped off and shorter windshield and side windows. It is a special one-off model made by Mitsubishi for this movie.
This was the first "Operation Condor" movie, but for the US release it was titled "Operation Condor 2" because it was released after the second movie. A new musical score was created by Michael Wandmacher for this release, as well as an English dub (with the participation of Jackie Chan).
This movie was filmed on location in parts of what was then Yugoslavia: Zagreb (Dolac Central Market), Upper town, Trnje (near the then-unfinished building of Croatian Radio Television), Croatia, and Predjama Castle near Postojna, Slovenia. Filming was also undertaken in Graz (Austria), France, Spain and Morocco.
