Josh OConnor Kelly Reichardt Mastermind.

Josh O’Connor stars in four films this fall, including the New England romance “The History of Sound,” with Paul Mescal; “Rebuilding,” in which he plays a Colorado rancher whose home is taken by wildfires; Rian Johnson’s whodunit “Wake Up Deadman: A Knives Out Mystery”; and Kelly Reichardt’s “The Mastermind,” a 1970-set heist movie. It’s a convergence of movies that cover a wide range of terrain, showcasing O’Connor’s rangy talent and innate, scruffy soulfulness. If “La Chimera” or “Challengers” didn’t already convince you, this season should be a veritable onslaught of O’Connor’s loose leading-man magnetism.
