The Graduate 50th Anniversary (1967) presented by TCM

Fathom Events, Turner Classic Movies and Studio Canal are bringing The Graduate to select cinemas nationwide for a special two-day event, which also includes an introduction from a TCM host. Dustin Hoffman's Benjamon Braddock, adrift after college, is craftily seduced by Anne Bancroft's icily-assured friend-of-the-family Mrs. Robinson.

So it's understandable that Ben's dream girl Katharine Ross is a bit startled to learn that he's sleeping with ... her mother.
