Sword stained with royal blood is a movie with a very weird story. The action scenes are numerous but they are far too short to satisfy a swordplay movie fan. And Yuen Biao doesn't even let us the chance to see his martial artist capacities. But the end fight is well orchestrated with the wires as you witness an aerial fight between two men , for real ,without seeing the wires. This movie remains good to rent but no to buy, buy Duel to the Death or Swordsman II for a good swordplay movie instead. 7,1/10
