At an age when many actors are slowing down or long retired, Anthony Hopkins has kept up a feverish pace, with recent roles including Pope Benedict XVI in “The Two Popes” and Odin in Marvel’s “Thor” movies. In his new film, “The Father,” Hopkins’s character, Antony, is beginning to suffer from dementia, but he doesn’t want to accept a caregiver when his daughter, played by Olivia Colman, can no longer live with him. The film brings the viewer into Antony’s experience, particularly his confusion about what’s happening around him. Hopkins tells Michael Schulman that he hasn’t dealt with dementia in his own family, thankfully, but that he wasn’t daunted by the role. “When you’re working with a superb script, it’s a road map, and you follow it,” he says. He advises younger actors, “Don’t act too much. Keep it simple.” Plus, the writer Patricia Lockwood, who’s just published her first novel, on how she created literature out of the fractured consciousness of an obsessive Twitter user.
