Anthony Wong said his son was less than impressed by his use of a body double in Ip Man: The Final Fight.He had attended the Ip Man: The Final Fight descriptive narrative service film appreciation event organised by the Hong Kong Society for the Blind yesterday.Anthony revealed that his older son questioned his use of a body double. "I asked my two sons, did my fighting look good. The older son said pretty good, but the leg wasn't me. It was a double's. He told his mother that normally at home I wasn't so agile because at home I was 'one with the bed'. "I was mad and immediately challenged my son, only then did he believe me." The film's box office has already exceeded HK$5 million, and he said that he was very satisfied with its reception. Anthony also said he was rather confident about playing Wong Fei Hung because he was familiar with Kwan Tak Hing and Wong Fei Hung. He also knew a little Hung Kuen, but he would have to lose weight first. He joked, "I now am a Tai Chi master, a fat guy."
