How did the prosthetic leg in Andy Lau Bomb Squad 2 come out? In fact, the crew of Shockwave 2 is also very attentive to props. There are four kinds of prosthesis in Andy Lau: temporary prosthesis, carbon fiber prosthesis, aluminum alloy prosthesis and intelligent prosthesis.

In Pan Chengfeng's rehabilitation shot, a temporary prosthesis is used. Legs wrapped in green cloth stand upright and jump to walk. In the hospital or at home, you should expose the position of the broken leg and perform the lens of inner contradiction. There are ferocious scars on the broken leg. At this time, carbon fiber prosthesis will be used. Aluminum alloy prosthesis is used in outdoor chasing and other scenes. Because of the need of the plot, Ma Shijun, the villain in the play, gave Pan Chengfeng an intelligent prosthesis, and he also hid a camera in it.

Finally, in the process of post-production, post-producers need superb and patient matting skills to trim the green part of the whole picture and achieve a natural and realistic state in the process of watching movies now. It can be said that "The Resurrection of Hong Kong Opera", a well-received and box-office masterpiece, embodies the painstaking efforts of the whole crew.
