Remember when disney played 3rd party movies?

Mostly when I mean 3rd party I mean from another studio. A couple I remember way back is some that were rated G to PG 13, I remember one that was rated R but they cut some major parts in it. I dont remember what it was called but my couisn always watch it. Oh yeah they played super mario bro's, lol. They the first 2 superman movies before it started 2 suck.
