The Fairy King is a 1998 British family fantasy film on DVD, directed by Paul Matthews.
Since birth, Kyle and Evie Preston have been told stories by their grandmother about battling giants who trapped the last of the world's fairies underground many thousands of years ago. When their Grandmother dies, Kyle and Evie inherit an old gold mine and family house that they didn't even know existed. Little do they know the mine is actually keeping fairies trapped and if not set free, they will be lost forever. It's a race against time as the trapped fairies hold the cure to a terminal disease which has befallen the kids' father (Corbin Bersen).
