The only American Ninja film to be part of the action-comedy sub-genre.
Now you shall taste my poison!
Throughout the film Lisa (Anne Dupont) doesn't wear any jewelery. When she is kidnapped, she is unconscious and carried away by the villain and is clearly wearing a metal watch on her left wrist. However, she was not wearing the watch up to the point where she is snatched by the villain and it's gone by the time she regains consciousness.
U.K. video version is cut by 1 minute and 11 seconds to remove all fight scenes featuring nunchakus and throwing stars, and to edit an ear clap and a scene where young Hiro is kicked in the head.
