THAT FUNNY FEELING (1965)

Sandra Dee (Come September) stars as Joan Howell, a young and pretty maid-for-hire, who meets and begins dating wealthy New York City businessman Tom Milford (Bobby Darin, Hell is for Heroes). Embarrassed about taking him home to her tiny apartment, Joan brings Tom to a swanky apartment she cleans - not knowing it's really his place. Tom carries on the deception until Joan discovers who he really is and sets out to exact sweet feminine revenge in this madcap romantic comedy of mistaken identity.
