Who Gets Top Billing?

[hamlet2003]

I've noticed that in his opening to each episode, E.G. Marshall only mentions one or two of the actors at most. Often he only mentions one actor even though there are other noted actors who appear in the episode. I noticed in the episode "The Colony" only Tony Roberts is mentioned even though character actress Frances Sternhagen is also one of the actors. (perhaps she wasn't so well known back in the seventies?) Just curious on anyone's thoughts about why the whole cast is never mentioned, as usually the case with modern radio dramas such as Hitch Hiker's Guide or the Star Wars dramatizations.

Brian,
Great question. I've wondered myself and though I don't have so much as a theory, I'd be interested to know what was behind the billing. Thanks for posting this question.
