Am I the only person that thought at first that Lucius was played by Roger Daltry? I wasn't sure though since there was something a bit off with him that could easily be makeup. I finally checked the credits and saw that he was actually played by someone named Phil Davis. Nothing of his work sounds familiar to me yet I swear I've seen in him before, which goes back to me thinking he was Daltry.
I loved the (plaque?) of the Doctor and Donna as the family's household gods. The art department did an amazing job with it.
