The Apartment was named one of the 100 best movies of all time by the American Film Institute. It stars Jack Lemmon and the adorable Shirley MacLaine, and it's set during the days between Christmas and New Year's Eve! Now is the perfect time to watch it!
I love this movie so much. Jack Lemmon! Shirley McClain! Tennis racket colanders! Love! Hilarity! (Also some really dark stuff like infidelity and suicide attempts... because all really great movies have both light and dark, right?) Really, it's such a fantastic film. You can't go wrong with something directed by Billy Wilder and starring those two superstars.
