Hello
I have uploaded some clips from 'Slayground', a feature film which was
partly filmed at Southport Pleasureland in 1983.
Download it here: http://www.conceptnews.org/download/sg/slayground.zip
There is a fight scene under the Cyclone and also the inside of the
river caves is featured. Some other parts of the film show Blackpool
Pleasurebeach area but it is all supposed to be the same place. It
actually says the film ends in Blackpool on this review:
