The Playbirds

After being hurled into the swimming pool near the end of the movie by Alan Lake, Diane Foster was taken to hospital, having hit the bottom of the shallow end. The cast seen diving in were attempting a genuine rescue and was not scripted. The ambulance arriving when the scene cut to outside the house was real and was left in the movie. This was documented in a News of the World feature later.
