Bonus points if you noticed the Ellen picture Saul burned a cigar through in the pilot (David Eick's wife, Jennifer) is a different person than the series (Kate Vernon)... except in a "Previously..." shot where they changed it to be Kate.

Just wondering, are you at all familiar with the cheesy 1978 television series? Despite growing up with that original, I found the Ron Moore version utterly surpassed it in every way... even though they changed the frakkin' helmets.
