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.

Josh O’Connor is in Cannes for the world premiere of Kelly Reichardt’s latest, The Mastermind, which received an 8-minute ovation.

Rising British actor Josh O'Connor was drawn to how normal his character in "The Mastermind", a suburban dad who cooks up an art heist, seemed when he signed on to U.S. director Kelly Reichardt's new film that premiered at the Cannes Film Festival.

Jauntier than any of Kelly Reichardt’s previous work, “The Mastermind” packs an ironic punch. That the title need not be taken literally becomes clear right from the start, of course; that the film’s shaggy-dog tone belies something far-sadder and more allegorical takes a bit longer to set-in.

Josh O'Connor plays a hapless art thief whose big job goes wrong in the 1970s-set thriller, which premieres in the Cannes competition on Friday.

Kelly Reichardt's latest film "The Mastermind," starring Josh O'Connor as an art thief on the run, earned a 5.5-minute ovation at its Cannes premiere on Friday night. The applause brought Reichardt to tears,

The title of Kelly Reichardt ’s “The Mastermind, ” the last film to premiere in competition at Cannes this year, only gets funnier the more you think about it. Josh O’Connor stars as J.B., a judge’s son and former art student who hatches a plan to rob a handful of paintings from a museum in Framingham,

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.

Like so much of Reichardt’s output, The Mastermind feels modest when you’re watching it and downright brilliant once it’s had some time to settle in your mind. Her films are so present and unguarded from moment to moment,

The historical drama, from 'Living' and 'Moffie' director Oliver Hermanus, premiered in competition in Cannes Wednesday night.
