An Eye for an Eye

The producers originally wanted to cast André René Roussimoff, more commonly known as Andre the Giant, in the role of The Professor (Professor Toru Tanaka) because they felt Tanaka wasn't tall enough. They were eventually convinced that Tanaka would be more believable, as well as cheaper, and with less scheduling conflicts, so they agreed to cast him. In order to overcome his height "disadvantage", they had him wear platform shoes to make him appear taller than his 5'11" frame.

During the Triad assault on James Chan's house, Sean Kane attacks a Triad terrorist who knocks an ornamental box off a desk as he falls. When Kane runs for the door, the box is back on the desk again.

Most European versions of the film omit the shower scene between Norris and Maggie Cooper and cut straight to the boat fight sequence.

Edited into The Green Fog (2017)
