Cavorting by the sea in their mod haircuts and Nehru jackets, the title characters of this Japanese political satire (1968) oddly recall the Beatles in Help! When they emerge from the water after a swim, two of them discover that their suits have been replaced with schoolboy togs and a Korean army uniform. This wardrobe switch—the first of many—triggers a black comedy of confused identities and gender-bending that may have been audacious at the time but feels dated now. Director Nagisa Oshima (In the Realm of the Senses) has written that his filmmaking was reinvigorated by trips he made to Korea and Vietnam in the mid-60s as part of a TV documentary team; his antiwar stance is expressed most effectively in the final sequence, which quotes Eddie Adams's famous photo of a Vietcong being executed on a Saigon street. In Japanese with subtitles. 80 min.
