Hi Chrissy,
I'll try go get in touch with the BFI as I still want to find back my missing movie. I now know it's not "Five clues to fortune". It is really strange nobody remembers my movie. I have tried several forums in different countries and nobody remembers. The only possible reply I've got is "Treasure at the mill", but it is not this one. I know that somebody else in Germany is looking for the same movie as me. I have tried to get in touch with him but I didn't get any reply. I guess he doesn't check his replies anymore as it is quite an old forum.
Of course I will let you know when I find it back. I am very curious to know which film or series it is.
Thank you.
Tricy.
