The Sci-Fi Talk podcast has a talk with Jamie Bamber:
Taped at the Icon 26 Press Conference, Jamie talked about the season three finale before it aired that Sunday night. He also hints about a fifth cylon. He also chatted about his character of Apollo plus working with Edward James Olmos and Richard Hatch. He even discussed his role on Ghost Whisperer. Some good insights but no spoilers.
The podcast is also on iTunes.
