In a convention Q&A on Valentine's Day, Karen Gillan discussed her final moments shooting with Matt Smith and Arthur Darvill:
I remember the last thing we shot was in the episode The Power of Three... iIt was just like a normal shot of us looking outwards, outside the TARDIS, and we had to one-by-one go inside the TARDIS. So it became this really symbolic moment where Arthur went in, I went in and then Matt went in, and they shouted "cut" for the very last time. And we all just like hugged in the dark in the TARDIS. It was like such a beautiful moment, actually.
