The Apartment/YMMV


 * Comedy Ghetto: Managed to break out and win Best Picture (though it's more of a comedy-drama).
 * Tom Hanks Syndrome: Fred MacMurray was mostly known for comic roles until Billy Wilder cast him against type in Double Indemnity and The Apartment. MacMurray reckoned these were his best performances.
 * The Woobie: both the lead characters, C.C. and Fran.
