Since I've been on jury duty for three weeks now (!) counting the days it took for them to pick the jury, I've been thinking of 12 Angry Men, which started life as a live teleplay
, then became a movie
and a play
. All written/adapted by Reginald Rose
, whose name I never remember hearing before.
You can watch the definitive version, the 1957 movie starring Henry Fonda (and a young Jack Klugman) and directed by Sidney Lumet for free on Youtube.
It's a tightly-written, excellent piece of work. I will have more to say about it, and the case I'm on, after the case has concluded.
