During the infiltration of Don Steffano's winery, the picture taken to fool the security camera was taken with a Polaroid instant camera, which has a big white border at the bottom of the picture. The picture was taken with the camera right side up, which means that the border at the bottom would mean that the picture would be right side up. But on the rig they put on the security camera, it is shown that it is holding the instant picture with the white border at top, meaning the picture is upside down, but is shown as right side up through the security camera.
In one of the fight scenes Jones takes on Pinky's goons when they sneak into his dojo at night. Jones has his friend switch the lights on and off in three second intervals, striking when the lights are on & evading when off. During one of the "lights on" intervals Jones is seen wearing the cap of one of the intruders, having obviously taken it from him while in the dark. However, a little bit later the same hoodlum can be seen in the background wearing his cap again.

Obvious stunt double for Jim Kelly towards the end when he does the butterfly kicks to take down the four thugs, who are also pretty much just standing there waiting to be kicked in a moment that is not well choreographed.
The stunt double even has a deeper skin tone than that of Jim Kelly's.
