The two martial arts scenes of the film were experimentally made into 3D movies. In order to achieve the best 3D effect, part of the martial arts scenes were filmed with a 3D camera, and the most realistic action combat was condensed into two 3D martial arts scenes of 20 minutes.
According to reports, due to the many and fast martial arts movements, the many contact points of the characters, the costumes, long hair, etc., to make 3D effects, you need to draw them layer by layer. Each frame of film must be drawn at least 4 layers. Woo Ping Yuen aims to create 3D. The effect specially invited more than 100 special effects personnel who had created " Iron Man " and other films, and it took half a year to complete. And the two shots of 3D have higher requirements for the actors, requiring the actors to punch to the flesh in the martial arts action.
At the end of the film "A Thousand Snake Cave Showdown", after the pursuit of perfection, Baye Yuan ordered the crew to rebuild a 30-meter-high, 3-story well-deep ancient well in Hong Kong.
