I think it's safe to say that UP is pretty up there on everyone's favorite kiddy movie list. I don't know of anyone who didn't like it actually--really one of Pixar's greatest.
I'd like to think it's coincidental, but there could be a possibility that his parents overfed him after seeing UP so he can be a real-life Russell. Afterall, who wouldn't want a Russell offspring to help you cross your porch?! I sure wouldn't mind....
I don't think those balloons will help him fly to South America.
