Whenever I’m watching a movie like “Beirut” (2018), where nobody changes clothes for days and the sun is beating down, I’m thinking how bad I’d be smelling and how much I’d want to take a shower. But I also pay attention to the plot, because it’s like a big game of poker where the winner is always the person who doesn’t give a shit the most. If I were Jon Hamm, I’d be pretty happy at my transition away from TV (and far away from “Million Dollar Arm”) to a starring role in a major espionage thriller alongside Rosamund Pike.
