Yes, Samfan, that was the real Christopher Foyle of Foyle's Books. He was invited to do a cameo that should’ve taken a few minutes to film, but as he confessed in an interview, his nerves over being on camera got the better of him, and he kept saying, "Good evening Michael," over and over again. Took about a dozen takes before he managed to call MK 'Christopher.' He said MK was very gracious and never showed his annoyance.
