This is really brilliant. (I suspect you need to have seen both movies - "Inception" and "Up", that is - to really appreciate it, though.)
What's amazing is how well it all fits. Who thinks of this stuff?
(I've seen "Inception" twice, by the way, I loved it. And I love "Up" so much I've watched it repeatedly on video, which is something I don't do a lot.)
Hmm, I think my super-narrow format is going to cut off a good bit of the video. You may want to click over to the original source.
