OK, so I'm curious: is this spot dedicated to just the 1939 film, or what? I'm trying to get a sense of how this is distinct from the link, and it seems like this is focussed entirely on that one film. Is that right?

I'm guessing this spot is dedicated to the 1939 film and the Oz spot is dedicated to anything related to Oz (i.e. every story Baum wrote about Oz, the Gregory Maguire novels, Wicked the Musical, The Wiz, the miniseries Tin Man, etc.)
