I don't know how much stock I put into that theory, because the rumors of Walt Disney's body being frozen have been going around for decades, pretty much ever since Walt died. Seems strange that they'd wait until 2013 to release a movie in order to change the search results because of the persistent rumors. And even if Walt did have his body frozen, who cares? I mean, yeah, sure, in 1966 it would have been a strange thing for someone to do, and even today having your body frozen after death is still kind of a weird fad, but it's not like it would need to be some incredibly huge secret. I personally don't give a crap one way or another if Walt were buried or frozen.
