Woman Prison (1988)
One thing screenwriter Nam Yin learned early in his career was that if you find a good story you can turn it into a winning formula for continued box office success. You can look to the Troublesome Night phenomena to see a truly long lasting blueprint. He was lucky to have a major success with his very first screenplay, the torrid Prison on Fire, directed by Ringo Lam. 1988's Woman Prison is basically a scene for scene replication of his first film, recast with woman playing similar characters found populating prison life.
Presenters Eric Tsang Chi-Wai and Alan Tam Wing-Lun were no slouches when it came to recognizing easy money at the box office. The pre-production meeting between these two movie nuts, Nam, and director David Lam Tak-Luk must have been quite a high energy scene. They managed to put together an energetic cast to bring a gritty realism to the awful conditions of the former colony's female prison. Look for Maria Cordero and Liu Fan as guard and inmate, respectively. Woman Prison is quite compelling, with excellent production values and top-notch, emotionally engaging performances.
