At the time, Yuen and Donnie were interested in moving from traditional period films to modern police-type martial arts movies with a Miami Vice flavor. Part of their vision was to find highly qualified foreign martial artists who could add a contemporary urban feel, and express martial arts creatively at a high standard. Berwick was cast in three of these movies, which represent the early fruits of this vision. Exhibiting highly complex kicking techniques in these films, he earned the nickname 'Vicious Legs.' Although Berwick was set to portray a 'good guy' role in another film, the Tiananmen incident of 1989 lead to the significant delay or shutdown of many large scale Hong Kong action cinema projects. After waiting in vain for the project to begin, Berwick decided to end his acting career and returned to the United States. With the experience gained in the film industry, he has performed, written, edited, and narrated instructional martial arts videos and other media.
