Hmm. I watched the cast videos and didn't have to sign in. If you are able to watch, beware. You'll have to sit through a 30 second ad for each video.
Hmm, that’s weird. I kept getting CBS pop ups to register. It wouldn’t let me watch the short premiere clip through your link above but it did when I did a search for it. CBS doesn’t have the cast interview videos listed on their top tab but (IIRC) down on that page with the 30 minute round table with Jeff. I think that’s the page that keeps giving me grief. Even the bio pages kept shorting out like they were on a timer. Never saw such goofiness before. Oh, well.
