The last time I saw Casey Affleck was after an 8:30 a.m. Sundance Film Festival screening of “Manchester by the Sea,” which left my colleagues and I so emotionally drained we were pretty much useless for the rest of the day. Affleck finds this very funny. “Oh man, that’s awesome,” he laughs. “That was a tough screening. At Sundance I’m usually just going to sleep at 8 a.m.” We’re talking on the phone a few days after the festival’s virtual premiere of his latest movie, “The World to Come,” which made its Sundance debut last month under very different circumstances. “It’s so strange doing these things sitting in front of your computer,” he sighs.
