Notes
This is, as usual for a Godfrey Ho ninja movie, a cut-and-paste using another movie, Don't Love Any Stranger as its base.
In addition to that, there appear to be multiple speeds of this movie, mainly due to PAL-NTSC conversion errors.
The Longest version is 1:28:24, where the movie proper starts at 0:00:06.
(There's another edit that includes a video production logo - it's 1:28:27, but the movie starts at 0:00:08, so it evens out more or less with the Longest version.)
There's a Spanish edit that's 1:27:08, where the movie starts at 0:00:17.
The Shortest version is 1:24:41, where the movie starts at 0:00:05.
Not finding content-based changes, eg no shots are missing, these are really playback speed differences.
