Perhaps Brown was not the easiest director to deal with for busy actors who worked elsewhere, like my favorite Lloyd Bochner, and perhaps some found out radio just wasn't their cup of tea. After all they could make much better money elsewhere. The repetition of actors also suggests a kind of closed shop where you had to be good buddies with the others or you wouldn't be cast. I would like to have heard more of Theodore Bikel, Bochner and others instead of Fred Gwynne so often myself.

The gig only paid Union scale of $73.50 per show for each actor, so it was really a sideline for everyone except Brown, and as a result, not something an indemand actor might pursue. However, writers could earn $350 a script, which explains why many known CBSRMT actors also received the occasional story credit...Sam Dann, Ian Martin, William Redfield.
