For the past few years I have been trying to find a movie from when I was a child.

Its about a young girl (maybe teen or little older) she goes through a mirror or some sort, I know there Is a jester or joker in this movie, at the end of the movie there is some sort of wedding or party going on and she has to go back home, but when she goes back through the mirror the jester/joker is cry saying he doesn't want her to go back, (I think she wakes up) and she has a little doll of this jester/joker.

It is a movie with people no puppets I think

I has a alice in wonderland / wizard of oz feel to it

This sounds like a film of Alice in Wonderland that I have seen a long time ago. I don't remember the joker but I remember the girl walking through the mirror. It could be this one, but I am not sure:
