I don’t remember whether it was a tv show or a film but I remember there being a girl (red head) who was kept captive by this gypsie woman who kept her chained up at a bird and then this guy rescued her and when the gypsie found him she turned him into a ferret at one point I don’t remember the ending or much else thanks for the help ☺️
Sounds like: Stardust (2007) – http://www.imdb.com/title/tt0486655/
