This is the second movie to be released on Netflix at the same time as in theaters, after Beasts of No Nation (2015).
Unlike the first film which was shot with Mandarin dialogue, English is used to portray the story. The first film received much criticism from Chinese viewers due to the fact that only one of the four main characters spoke Mandarin fluently. It is possible that in order to avoid a similar review and maintain the freedom to cast whomever they chose, producers went with English dialogue.
Michelle Yeoh is the only main actor from the first film to reprise her role. Woon Young Park also reprises his Thunder Fist character.
The voice in the trailer says the lyrics of the song "Bad Moon Rising" by Creedence Clearwater Revival.
This is also the second time Michelle Yeoh and Eugenia Yuan share the silver screen. Yuan played Hatsumomo's friend Korin in Memoirs of a Geisha(2005), who helps her trick young Chiyo into destroying the kimono belonging to Mameha, played by Yeoh.
The film's director, Yuen Woo-ping, served as the action choreographer for the first Crouching Tiger, Hidden Dragon film.
Second collaboration between Michelle Yeoh and Donnie Yen, after Wing Chun (1994). Coincidentally, they play lovers in both of these movies.
In the beginning of the film, Shu Lien says that 18 years have passed since the passing of Li Mu Bai at the end of the first film. In reality it's been 16 years since the first film was released.
This movie connects the master & student cinematic relationship story of Bruce Lee. This movie's villain, Jason Scott Lee, played Bruce Lee in Dragon: The Bruce Lee Story (1993). One of the main protagonists, Donnie Yen, plays Bruce Lee's master, Ip Man, in Ip Man (2008), Ip Man 2 (2010), and Ip Man 3 (2015).
