“I like theater because it’s so unprofitable,” said Annie Baker in one of the rare interviews she’s given. “The only reason to do it is to make something surprising and strange.” Baker’s plays are known for long length, quick and clever dialogue, and anti-theatrical settings. Take The Flick, which earned Baker a Pulitzer Prize in 2014. Set in a run-down Massachusetts movie theater, three employees chat as they mop up spilled soda between screenings. Not much is known about Baker’s latest play, Infinite Life, other than the basic plot: five aging women discuss their failing bodies while reclining on chaise lounges. James MacDonald, who has previously collaborated with Baker, directs the premiere. —Jensen Davis
