Visible crew/equipment: During the final fight scene where Jackie takes on the Amazonian women, there are several shots where dressed up stuntmen double for the women.
Revealing mistake: When Jackie jumps on the hot air balloon, he is supposed to be REALLY high in the air. Still you can see tops of trees on the lower right corner of the screen.
Continuity mistake: At the end where Jackie jumps from the side of the cliff to jump onto the hot-air ballon he starts off only a couple of hundred feet from the ground. Then in the next scene he is a couple of thousand feet up, like he has just jumped from an aeroplane.
Continuity mistake: In the first scene where Jackie is stealing the sword in Yugoslavia he hides behind a statue which has the sword whilst the natives pray to the statue. Jackie knocks the head of the statue off and it rolls to the ground just in front of the leader with the face pointing in Jackie's direction. But when the camera shot changes to the leader, the face is now facing the leader instead.
Continuity mistake: In the scene showing Jackie Chan stealing the sword from the tribe he grabs the items and swings up onto a high wall of the castle before turning, jumping off, grabbing a tree, swinging some more and landing at the top of a steep hill and sliding down. When he jumps he has short hair, when he lands his hair has grown about 2 inches. As you can see in the end credit montage this is because he fell off the first time and nearly died. He had to recover, go back and do it again.
Visible crew/equipment: While chasing the two motorcycles the front of the car is open and a wooden frame is visible with a movie camera. (00:34:55)
