I apologise to Emma Thompson.

I thought she was Helen Mirren. I mistakenly thought Helen Mirren played Professor Trelawney and Nanny McPhee. Oh well, I'm pleased it was actually Emma Thompson.
She's great. Although I didn't realize that she played Doctor Crippen in I Am Legend. For those who haven't seen the slow and actionless film, Ms. Thompson is single-handedly responsible for the death of what, 99% of humans on the planet?
