His previous works, such as "New Police Story", "The Kid", "Who Am I", "Twin Warriors", and "Shanghai Knights" all have strong local characteristics of Hong Kong. However, his new work "Keep Talking" is adapted from the Hollywood movie "Cellular". Many people think that adaptation is an easy job standing on the shoulders of others, but the fact is just the opposite.
