Odd subject, I know, but my curiosity's driving me crazy.
There's one commercial, from a few years ago, that raised the same question in my mind every time I saw it. I finally looked it up on YouTube, to get a better look; it's under the title "Passages Malibu - 2011 TV Commercial". About eight seconds into it, is that actually Summer Glau, or just an incredible look-alike? The credit's not on her IMDB page, but I'd swear that it's her. (If it is, the guy with her must be pretty short - Summer's only about 5'6".)
