"The Last Letter" opens up after the arguements in a serial murder case have wrapped up and the jury deliberations begin. The facts seem cut and dried, and eleven jurors are convinced of the accused's guilt, but there's one holdout, and he sets out to change the others's minds. With the exception of some flashback scenes showing how the various murders are presumed to have been committed, the whole thing takes place in the jury room, in real time. I was impressed how they managed to keep the whole thing fresh, tense and engaging within those constraints. The subtle (and sometimes not so subtle) clashes between different personalities within the jury room is handled well.
