Edward James Olmos at the UN
Battlestar Gallactica intro done in the style of The Office
Rather lengthy (and kinda dark-visually as well as content-wise, of course!) summary of first three seasons, but VERY well done
Time lapse video of drawing of Tricia Helfer
BSG on Robot Chicken
Bear McCreary is one of the BEST damn composers for TV/video games/etc. He is capable of blending so many different styles, it's just mind-boggling. Here's a song he wrote for BSG (performed live), All Along the Watchtower, A Distant Sadness (I wonder if it's true the lyrics to that are Armenian...)
Damn. I'm going to miss that show. I hope Caprica has something similar to offer.
