Metallica's first-ever performances in China, which took place last Tuesday and Wednesday (August 13th and 14th) at the Mercedes-Benz Arena in Shanghai, have been filmed for a documentary about the trip. Metallica drummer Lars Ulrich revealed that information during a press conference in Shanghai, saying, "Being here in this wonderful country and feeling the energy and excitement, the idea came up to celebrate it and to try to document it and to try to get the experience out . . . there may be 20,000 of you who came to this arena yesterday and today, so we figured that if we filmed and shared the experience then maybe we could get to more of you and maybe there could be a next-level relationship between Metallica and China that could last for decades."

Ulrich added that plans for the film possibly included "bringing some local bands into it and bringing some actors in and maybe some way bridging this into the Through The Never movie that we made in the United States."

It is not clear whether the proposed documentary would be a China-only release or would also be available in the rest of the world.

Metallica's first show in China sold out in record time and faster than any other Western act that has played the country before.
