Ninja in the Dragon's Den has title music that has aged badly but the film itself has not. The martial arts choreography from Corey Yuen is sublime to watch and this film really shows off how good he is. Sanada who plays the ninja is perfectly cast, he also appeared in recent years as a samurai in 'The Last Samurai'. Conan Lee also had a cameo in 'Lethal Weapon 4'. Not forgetting super kicker 'Wang Jang Lee'. This is probably the best ninja film you may ever see. Great displays of agility, weapon craft, and stealth which is sadly lacking in ninja films of recent years. Great film and a continuously superb addition to that Hong Kong Legends collection.
