The Horizontal Lieutenant is a 1962 American romantic comedywar film, based on the 1961 novel The Bottletop Affair by Gordon Cotler who was a Japanese interpreter for US Army Intelligence during World War II.[3] It is a military comedy about an unfortunate army intelligence lieutenant who finds himself isolated on a remote island army outpost during World War II.[4] It stars Jim Hutton and Paula Prentiss and was directed by Richard Thorpe.
2nd Lt. Merle Wye, an Army Intelligence officer stationed in Hawaii, is rendered horizontal when struck in the head by a foul ball while playing for his unit's baseball team. In the post hospital he is attracted to Lt. Molly Blue, a nurse he once knew in college. His superior (and manager of the team) orders the inept Merle to distant Rotohan, a Pacific island liberated from Japanese occupation some months before, ostensibly to relieve Lt. Billy Monk, who has been unable to capture a Japanese holdout called Kobayashi suspected of pilfering military supplies. However the coach really wants Monk, a former professional baseball player, for his team. By claiming to be ordered to dangerous duty Merle tries to seduce Blue; when she discovers the ruse, she barely gives him the time of day.
On Rotohan, Merle and his Nisei interpreter (and lothario) Sgt. Roy Tada team up with Monk to flush out the wily thief hiding in the hills. Using a reluctant Tada as a "spy" they discover that Kobayashi has been stealing the supplies, all creature comforts, to feed and clothe his pregnant girlfriend. But Merle is distracted when Blue is also assigned to his camp. With the Navy, in the form of obnoxious Cmdr. Jeremiah Hammerslag, also hunting Kobayashi, Merle is threatened by his new superior, Col. Korotny, with another transfer if he does not capture Kobayashi soon—this time to an even more remote rock with only six other soldiers as company.
While romancing a local girl, Akiko, Tada discovers that Kobayashi is not even a soldier but a former circus performer hidden in a cave in the hills by the villagers. That night Kobayashi is to appear at a variety show staged by the locals to entertain the Americans. When Merle tries to arrest him, the agile Kobayashi stuns him using judo, knocking him horizontal again, and escapes. Col. Korotny tells Merle he is shipping out in the morning. During a drive in the hills to "say goodbye", Merle and Blue stumble on the cave, where Blue captures the acrobat after Merle once more becomes "the horizontal lieutenant". Merle is given a medal anyway and wins her heart.
