He'll recommend the best parts!
BTW, on the BBC TV mini-series, the DotD was played by Peter Davison,
better known from his work as Tristan on "All Creatures Great and Small," and probably best known as the 5th incarnation of "The Doctor," in the BBC series "Dr. Who."

I liked Peter Davidson as the Doctor. He had a hard act to follow.
And Trillian in the BBC series was (or hopefully, still is) Peter Davison's wife, as I recall.
