Just had to toss this in:
Being a fan of both Battlestar Galactica and the HBO miniseries Band of Brothers, I ran across this on YouTube today:
It's a fan-made title sequence mash-up which I thought was very well done (just ignore the typos).
In doing a Google search later, I ran across a link to two more mashup videos, brought to you on this posting on the acclaimed BSG-news and info weblog Galactica Sitrep.
At least, they are supposed to be there: the post itself is blank, probably due to firewall/anti-virus issues, so if someone looks at this and can get to the links, let me know how they were :-).
For a small bit of trivia, Jamie Bamber (Apollo) in BSG played a small role in Band of Brothers, so there's a small connection between the two shows.
