I'm a big fan of SF/F/Horror, and all things in between and out.
The story of Orson Welles adapting The War of the Worlds on the radio one Halloween and terrifying a ridiculous amount of the United States is kind of legendary today, but as someone who'd never heard it before, I wasn't sure if it'd live up to the legend or not.
It does, and it's a lot of fun to hear and imagine people listening to it when it originally broadcast. The moments of silence between reporters or military personnel when they go off the air unexpectedly just hangs there, and you can imagine the genuine dread that must've inspired (and still does, for those of us unafraid to use our imaginations).
I recently listened to Wells' original novel (narrated by Simon Vance) and I was impressed how much Orson Welles channeled that here - particularly the scene toward the end with the artillery man. It's a very solid adaptation, and a genuine piece of Americana.
It does sound like an old production, but it's well worth listening to if you've ever been curious about how Welles and Wells created possibly the best Trick or Treat in the world.
