Michio Kaku - The Universe in a Nutshell
Even as an avid science fan, I've learned more from this 40 minute video about the Universe from acclaimed theoretical physicist Dr. Michio Kaku, than perhaps the entirety of my knowledge of physics before seeing it. I cannot recommend it highly enough. Even if you are already a physicist, it's likely you'll learn something as well, even if it's only that Michio Kaku created his own particle accelerator in his garage when he was in high school. You know, normal teenage stuff. Don't forget to pick up Dr. Kaku's new book The Future of the Mind while you're at it.
