One of the fun inventions of screenwriter David Seltzer in Willy Wonka and the Chocolate Factory (1971) is how Willy Wonka is always quoting and mis-quoting snippets of poetry and literature.
Here are just a few bits that Wonka quotes:
“We are the music makers,
And we are the dreamers of dreams…”
—Arthur O’Shaughnessy, “Ode”
“…all I ask is a tall ship and a star to steer her by…”
—John Masefield, “Sea-Fever”*
—Ogden Nash, “Reflections on Ice-Breaking”
“The suspense is terrible. I hope it will last.”
—Oscar Wilde, The Importance of Being Earnest
“Where is Fancy bred… in the heart or in the head?”
—Shakespeare, The Merchant of Venice
In Pure Imagination: The Making of Willy Wonka, Mel Stuart writes:
Stan Margulies was charged with obtaining the legal clearances so that we wouldn’t be sued for the purloined lines, and he had some fun with it. He sent a copy of the final script to [producer David] Wolper’s attorney, Eric Weissman, with a note. “Mr. Wonka,” Stan wrote, “it turns out, delights in quoting famous pieces of poetry. Happily, most of them are from our good friend, William (public domain) Shakespeare, but his taste is wide ranging.”
