Character mistake: When Barry Lyndon is talking to his mother privately, while standing on the bridge overlooking the water, Barry's mother refers to Barry's son Brian as being "at the mercy of his stepbrother", meaning Lord Bullingdon. They have the same mother. Lord Bullingdon and Brian would be half brothers, not step brothers.
Character mistake: In the first fight, there's a reaction shot where Speed shouts jubilant "Yes, yes!" when his own fighter misses with his attack and doubles over hit by a painful kick in the gut. That's a mighty weird thing to cheer on. (00:07:00)
Character mistake: In the fight in the Shaolin temple the Bruce Lee impersonator fights 4 monks who are supposed to attack him simultaneously, and they do, but Miss amazingly obvious openings, to the point of spending long seconds hopping around without attacking. Many martial arts movies feature as Common Mistake the main character facing multiple enemies that fight quite inefficiently, but few are this obvious when it comes to waiting a cue. (00:13:00)
