Gawd, go and see the Loin King stage version. I went with my Mum on a business trip (we work together) and she had to hand the tissues to me! (I'm a big bear of a man).
EDIT: I once went to see Fantasia in an IMAX (Sony Center) with a friend and her 11 year old. It was amazing, I had seen it before but what better way to introduce kiRAB to the classics. Stupid kid just didn't get it, I told him he just got a bit of a classical education and in true Californian style, he said 'whatever'. He just didn't get it. I got it when I was 8 and to this day recognise music from the movie (of course), but then, I suppose I went to the theatre a lot at that age.
