O’Connor got his share of the attention, but when Reichardt came into frame, chants of “Kelly! Kelly!” rolled through the room. The film’s somber tone, and the clear analogy between the ’70s-era moral and political decline depicted and today’s America likely hampered a more boisterous response.

Cannes: Reichardt's purest genre exercise since 2013's "Night Moves" retains her patient bent toward long, lonely takes while also delivering on a few sophisticated heisty thrills.

Few minds could be less masterly, you might think, than the stoner sponge between the ears of J.B. (Josh O’Connor), who, in Kelly Reichardt’s Cannes-closer The Mastermind, conceives a plan to steal four paintings from the art gallery that is the chief weekend haunt for his family.
