I've always been a huge fan of the Orson Welles Halloween prank radio broadcast of War of the Worlds. I make a point to share it with my classes each and every Halloween, and we talk about how prone to panic most of us are most of the time.
This television show demonstrates that quite nicely. A friend put me onto it. It features a lot of young talent and is hosted by Edward R. Murrow. See if you can spot Warren Beatty, Warren Oates, Ed Asner, and James Coburn as this production rolls along. I thought I saw John Astin too, but the credits don't give that name.
