Did you mean to say "Father Goose" with Cary Grant and Leslie Caron? Grant is an enemy plane spotter coerced into working for the Brits on a secluded South Pacific island, and ends up falling in love with Caron, who is a school marm with a half dozen or so young ladies under her care.
One of my favorites also, along with "Red Dawn", "Braveheart" , "The Great Escape" and "Apocolypse Now".
