From an interview with William Simpson and about The Magus for BBC Radio 4

Have you ever meet some of the actors on the set, and who left the biggest impression on you?

Yeah, I've met a lot of the actors. I guess Peter Dinklage, Tyrion made the biggest impression, as he's a truly brilliant actor...but then Lena Heady would always make a major impression, as I'd met her just after I'd watched the Sarah Conor series. We had a very long conversation about that! Charles Dance was very humorous when he popped his head over my drawing board and said, “you do all this? Very good, carry on!”
