Romantic comedy-wise this is the best there has ever been. Billy Wilder (SABRINA) wrote and directed this Oscar winner, which tells the tale of two people who get took and in the process find love.
C.C. “Bud” Baxter (Jack Lemmon, SOME LIKE IT HOT) is a low-ranking automaton at a huge insurance company in New York City. Through happenstance, his apartment has become the secret rendezvous for execs at his firm to take their mistresses, which often leaves him at work late or worse, sleeping in the park. He puts up with it, because these are powerful men, who can get him out of his little desk in a sea of little desks.
Like most of the men at the firm, he wishes he could take out the pretty elevator girl named Fran Kubelik (Shirley MacLaine, TERMS OF ENDEARMENT). Turns out she is having an affair with personnel director Jeff Sheldrake (Fred MacMurray, DOUBLE INDEMNITY), who finds out about “the apartment” and wants in on the action. With a promotion in sight, Baxter agrees not knowing that it’s Miss Kubelik that Mr. Sheldrake will be taking back to his abode. Sly wit seeps into every moment. With all the adulterous men coming in and out of the apartment, Baxter’s neighbor Dr. Dreyfuss (Jack Kruschen, MCLINTOCK!) asks if the iron man would like to donate his body to science.
