Recently reminded of this little gem after visiting its origins in St Michael's Mount, Cornwall. Loved this film as a kid. The attack on the ship was especially effective (I recall it being quite scary when I first saw it). The fact that there were 'scary' elements probably set it apart from the likes of the Sinbad and Jason films, and I guess this is this reason why its my favourite film of its genre and age. Admittedly the effects may look a little ropey nowadays but that doesn't get in the way of a very entertaining film. As much as I enjoyed it though, I can't help but admit that I wouldn't mind someone having a stab at a remake (this version will always be there if it goes pear shaped)
