A really great friend reminded me today that it was 75 years since Orson Welles infamous radio broadcast of HG Wells "War of the Worlds" which many Americans believed was really happening . You can listen to the whole thing here (in the UK anyway) , and there's a contest to celebrate the occasion here . This is probably the way to actually scare adults by presenting the story through a familiar medium as a news item.
Recently the Ralph Fiennes version of Shakepeare's Coriolanus featured the newsreader John Snow, and the Channel 4 disaster drama Blackout used this construct, and it can be very effective. It wouldn't surprise me if Welles did it deliberately.
Anyway I found the above version on youtube, so I hope it will stay there. So you can now listen fully aware that we are probably not being invaded by Martians. Have a wonderful night and enjoy yourself,
