It's 1967. The movie is Mike Nichols' "The Graduate," adapted by Buck Henry and Calder Willingham from Charles Webb's novel.
Dustin Hoffman, as recent graduate Benjamin Braddock, is talking with Elisabeth Frazer, as Joanne, a friend of his parents, when they are interrupted by Mr. McQuire, played by Walter Brooke.
Mr. McQuire's one-word recommendation to Benjamin brought gales of laughter in theaters - and still does, even though that word has proven to be eerily prophetic.
Joanne: "What are you going to do now?"
Ben: "I was going to go upstairs for a minute."
Joanne: "I mean with your future - your life."
Ben: "That's a little bit hard to say."
Mr. McGuire: (interrupting them) "Ben."
Benjamin: (to Joanne) "Excuse me."
Benjamin: (turning away from Joanne) "Mr. McGuire!"
Mr. McGuire: "Ben."
Benjamin: (voice trailing off) "Mr. McGuire."
Mr.McGuire: "Come with me for a minute. I want to talk to you. Excuse us, Joanne?"
Joanne: "Of course."
Mr. McGuire: "I just want to say one word to you. Just one word."
Benjamin: "Yes, sir."
Mr. McGuire: "Are you listening?"
Benjamin: "Yes, I am."
Mr. McGuire: "Plastics."
Benjamin: "Exactly how do you mean?"
Mr.McGuire: "There's a great future in plastics. Think about it. Will you think about it?"
Ben: "Yes, I will."
Mr. McGuire: "Enough said. That's a deal."
