Best Actor Nicholas Tse Ting Fung, Simon Yam Tat Wa, Shawn Yue Man Lok, Hu Jun, Andy Tien (On Chi Kit), William Chan Wai Ting and others starred in the Emperor Motion Picture AS THE LIGHT GOES OUT (GAU FOR YING HUNG), which will open in early January.
The film's final "dust explosion" scene was a major scene in the film. Playing firefighters, Nicholas Tse, Simon Yam and Andy Tien tossed flour into the air, then ignited the air to cause an explosion, and escaped through the resulting hole in order to bring survivors out of the fire.
According to a Hktopten report, the team used 30 bags of 25kg flour, which everyone inhaled. Andy Tien said that at night when he cleaned out of his nose, only white powder came out.
The film also used a lot of thick smoke to bring about a more realistic fire scene. The actors stated that working on the thick smoke scenes was very difficult. Simon Yam said, "This smoke really made us cough. After the shoot everyone in the body including the lungs were black."
Nicholas Tse's Post Production Office Ltd. performed the post production on the film. Nicholas Tse also said that the smoke post production was very difficult. "Smoke is the hardest to control, even harder than fire and water in post production. Thus this post production to me was a challenge."
Everyone put a lot of blood and sweat into making AS. Every actor trained until they were a size larger. shawn yue and Hu Jun would also arm wrestle on the set while Nicholas Tse would be their referee.
Nicholas Tse said, "Our team was a lot of fun, a very rare, healthy and united team. No one expected the seven or eight men would be together even when they ate. Even after the wrap we would still dine together."
