The Generation Gap - David Chiang (1973) - Shek Pik Prison, Lantau

Despite not being featured in the rest of the film, the opening scene of this film shows Ling Xi (Chiang) running down the entranceway into Shek Pik Prison. You may remember from a few posts ago that a similar view was used briefly in Police Force as Fung Hak-on describes a gang member (Fung also has a brief role in this film as a thug who tries to beat up Chiang in the middle of the film).

Police Force - Wang Chung (1973) - Shek Pik Prison, Lantau Island

Through the dead body they have recovered, the police identify a woman who knew the deceased and have been tracking her movements. In this scene, Wong's side kick recounts how she has been seen leaving Shek Pik Prison and we are given some footage of that with Fung Hak-on superimposed onto it as he is the recounting her movements.
