What is the name of this movie?

I don't remember the name of this movie (besides the fact that it's a narnia movie) but I know somewhere in the beginning the kids are in this house and they are playing hide and go seek, so the little girl decided to go into this wardrobe closet. Then she sees a door (I think) and she walks through entering a snowy world. This is all I can remember (it's been a long time okay!). Does anyone know the name of this Narnia movie?
