Stumbled on filming going on at Dublin Castle for The Tudors. The guys I spoke too weren't sure which episode it was (they think it 9-ish) but it's for season 4.
Since I haven't seen the show and don't know what's considered spoilery, I've put everything under a cut. There are pics and a video of the scene.
If you want to link back to this post, I've left it open, so feel free. If you want to repost the pics, that's fine, but please give credit.
ETA: Ok, for some reason the video isn't embedding... So here's the thumbnail to take you too it (yes, they do eventually do something. Towards the end :P):
