Twice this week I noticed guys getting up and presumably attending to business only a minute or two after a film has started. Who does this? It happened near the beginning of Wednesday evening’s Mindhunter screening at the Hollywood Arclight, and at the start of last Monday’s Blinded By The Light all-media at the Grove. Both times the evacuees didn’t return for a good four or five minutes. This is little dog behavior. Can you imagine a Manhattan theatregoer standing up and side-shuffling towards the aisle two or three minutes after the first-act curtain has gone up? You can take a break at the half-hour or hour mark, although moviegoers with a semblance of self-control rarely do this. I sure as hell don’t, in part because I don’t slurp Diet Coke out of 32-ounce containers.
