Yes, we know that Summer arrived at the multiplex three weeks ago with a certain superhero blockbuster, and the screens are slowly filling with more action franchise entries, raunchy comedies, and feature-length animated flicks. But that doesn’t mean a somber drama has to wait till the “award bait” clutter of the Fall and Winter. Particularly one based on “actual events”, and whose topic is a political “hot button” (the next presidential race is already heating up). This film belongs to a subset of “prison dramas”, stories set in the ole’ “grey-bar hotel” reach back into the silent days and were strong companion pieces to the gangster flicks in the early “talkies” era. That subset would be the “big house’s” final stop: death row. The focus being characters not doing “hard time”, but the “end time”, waiting for the “long walk” and hopefully a last minute call from the governor.
