Okay, so I was a bit premature when I said the previous post was my last because I just found another one worth including. It's actually from the final scene when Lee walks to the top of a wall, supposedly during the filming of Enter the Dragon, and the white suited karate dudes all turn around and salute him.
This scene was actually filmed in front of the famous Tin Hau Temple in Joss House Bay. The large courtyard in front of the temple was the area where the extras were lined up and it looks as though a temporary wall was built for Lee to walk up. The Tin Hau Temple itself is just off-screen to the left.
