The 'Iron Claw' movie is indeed based on a true story. It presents a fictionalized version of real-life incidents, staying true to the core essence while adding cinematic elements for entertainment value.
Eagle Claw Iron Skin was a Hong Kong martial arts film released in 1977. It was directed by Wu Siyuan and starred by Huang Zhengli and Liu Zhongliang. The story was set in the Shenzong period of the Ming Dynasty. It told the story of the Minister of Justice's serious plot to rebel. In order to eliminate dissidents, he planned to send Hu Long to sneak into the Liu residence to assassinate him and frame Xiao Rufeng, the brave general. The movie ranked 29th at the box office that year. The biggest attraction was the nine action masters, including Liu Zhongliang and Huang Zhengli. One of the classic scenes in the movie was the scene where the protagonist crushed an egg with his hands. Eagle Claw Iron Skin was also a success after it was introduced to the mainland, becoming one of the most popular martial arts movies of the year.
Iron Claw is not a true story. It's likely a work of imagination or based on fictional elements. Usually, such stories are crafted to engage and captivate the audience rather than being based on real events.
