Nothing to do with the Donnie Yen movie.

"Get your rusty gears on for Iron Monkey, the third actioner from director/martial arts star Yue Song (King of the Streets, Super Bodyguard aka Iron Protector) with a cast that includes frequent co-star Jiang Baocheng (Wrath of Vajra).

In Iron Monkey, Yue Song plays the role of “Thunder”, a lone, wandering warrior (you know, sorta like Mad Max or Kenshiro from Fist of the North Star) who takes on evil organization in a post-apocalyptic setting. The film obviously has no connection to previous, similarly titled films, such as 1977’s Iron Monkey, 1993’s Iron Monkey or 1996’s Iron Monkey."
