I'm trying to remember a fairy film I watched as a child. All I remember of the film is their being to children who find fairies at the bottom of the garden ( its not fairytale: a true story or an animation) and they help them get their home back ( I think it was a cave or a well ) which has been took over by some other creature, and in return the fairies help the children's dad get better ( I think he was dying) at the end of the film. I have looked everywhere trying to find this film, with no luck, I just hope someone else has watched this to haha.
