Movie #1459 (#249 this year): The Last Mile(1932, Samuel Bischoff)
Anti capital punishment film. Gritty drama first with prisoners being taken out to fry and then a prisoner riot with oodles more dead.
Very well made although it's kind of hard to tell due to the terrible copy from Internet Archives.
And the moralizing is kinda one sided. They make sure the main character is innocent and they never mention what the others did in order to get on death row.
