Ok, I've known this movie all my life but I can never remember the name or... anything much...

It's a version of The Frog Prince. The Frog is man-sized and teaches the princess... who's pretty young as far as I remember, maybe 7 or 8?. to dance by putting footmarks on the floor. For some reason this irritates the two older sisters who conspire to trap the Frog in a pit in the wood. The middle sister later has a change of heart and gives the little girl a lantern and map. Despite losing both she rescues the Frog.

I'm pretty sure I'm not mixing up movies; I have very clear images of certain scenes, but when I try and describe it to people no one knows anything! Please help?

It's the one with helen hunt as the sister, the frog prince (1986) - I use to love this movie, I still have it on tape!

Thank you! That's brilliant! Running off to Youtube...
