Rodney never spoke which is one major thing that made the episode so great; good writing and great acting just like Twilight Zones Eye of the Beholder.

Teachers using RMT in the classroom, I love it!  I use that episode with my grade 8 students when we learn about how authors develop characters. Very cool episode.  Been using it for years - the adaptation The Diamond Necklace compared with the short story, and The Black Room episode we compare to short stories The Bet (checkov) and The Side Bet. Lots of skills developed in listening to a story.   Lots of the students said they enjoyed the shows. We usually follow that activity with them adapting a Sunday cartoon to a mini radio drama. Have to consider ways to communicate setting, mood, character, etc to their audience. Always a fun activity. Not sure if any have formed a deep love for Audio dramas, but the have at least had some exposure, and they know about cbsrmt.com. haha
