Consider who you're talking to here; if even I think it's rule lawyering, it's pretty bad.
I'm not really sure what that's supposed to mean, but Galaxy said it himself. If it's disney it's good.
Muppets Treasure Island was co-produced by Disney even back then.
Up was long after Disney had acquired Pixar and Lasseter taken over animation, iirc.
edit: yup, just fact-checked. The acquisition of Pixar was 2006, Up was 2009. That movie is so disney your body can't take it.
