Island of Adventure was my favourite film when I was a kid, I have a DVD, copy from VHS which was copied from Betamax! so the copy is not great.
I have been trawling the web and so far I can't find a real copy of it anywhere.
Does anyone know why it would never have been released, or as far as I can see repeated on TV.
It had Wilfred Bramble in it!
