Well I can think of several movies. Most are based on British authors but I'm sure if you like Spooky movies, you'd like these...
The Owl Service...
Casting Of The Runes...
Children Of The Stones...
Stig Of The Dump...
Clay...
The Lord of the Flies (both the 1966 version and the 1990 version...
All of these films feature kids in them - not like the Goonies but sort of deliving into psychic, witchie type things if you are into that kind of stuff
Then of course as KevMartin pointed out, is the best of the lot - the complete Peter Jackson film of J. R. R. Tolkien's Lord Of The Rings - but do try and get the others - you'll be glad you did. They are like "The Last Navigator" which I've also got and is a beaut!
