Not to mention a killer/hilarious performance from the late, great Judy Holliday.It also contains one of my favorite "movie" apartments of all time.
Hepburn: "Now, when did you begin to suspect you were losing your husband's affections?
Holliday (with a wistfully lost look in her eye) Uh...when he started battin' me around.
Best scene in the movie - the 'slap' heard across the buttocks.
Hepburn: I'm not so sure it is. I'm not so sure I care to--expose myself to typical instinctive masculine brutality...and it felt not only as though you meant it, but as though you felt you had a right to. I can tell.
Tracy: What've you got back there? Radar equipment?
