I don’t see many people talk about this, but it’s one of my top ten favorite pieces of Batman media. The Knightfall BBC radio drama is absolutely amazing and extremely well done. The voice acting is some of the best out there and the Bruce/Batman voice actor is right up there with Kevin Conroy. The audio effects are just as good, this whole recording could be used for an animated film if they wanted to do that.
The whole thing is three hours long so it’s a bit of an effort to make it through, but well worth checking out.
There is also a podcast version.
