Secret Identities and Alter-Egos in Pop-Culture

To me, the whole superhero business boils down to secret identities -- alternate selves that encompass everything one wishes to be or hides from his- or herself.
I've always loved those Academy Awards segments where they show a montage on a particular theme. Through YouTube I've assembled a compilation of various clips that address the topic of alter-egos. What I'm currently writing for my own project focuses in part on this idea, so it's inspiring and informing me as well. But mostly, I'm just a big YouTube whore. Enjoy.
