The Hollywood News Report was invited to visit the Galactica Set while the filming of the season finale, episodes 19 and 20, were being filmed. Here's some of what they had to say: (Somewhat minor spoilers)
We toured the various stages, from the CIC to the hangar bay to Commander Adama's quarters - and everything in between - with publicist Carol Marks-George and production designer Richard Hudolin, both of whom were very generous with their time.

What we can tell you, is that the second half of season two promises to up the ante in every way imaginable. And for those who thought the rape scene in episode 210 was intense, Edward James Olmos informs us that it ain't nothin' compared to what's in store for the rest of the season.
