My advice to a first time director on how I direct radio drama. This is from a post I made to the radio drama e-mail discussion list . It's not too tough if you're well prepared. I happen to have much more detailed info on how I direct these groups at my Radio Drama Resources website. See especially my page about how to prepare scripts for production and the section on the nuts and bolts of production .
Amateurs lose much of their energy after a few hours.
You'll tire them out and believe me, you will hear the difference. I do ONE full rehearsal and then go live. A hungry crew is an grumbly crew. Make it a party. Your casting will be extremely important.
