Given a reference text about Being There, tell me when the book was published and when a film about the book was created.

Being There is a satirical novel by the Polish-born writer Jerzy Kosinski, published April 21, 1971.[1] Set in America, the story concerns Chance, a simple gardener who unwittingly becomes a much sought-after political pundit and commentator on the vagaries of the modern world. It has been suggested that Kosinski modeled the character of Chance after a former greenhouse manager named Jerry Jarvis who became the national leader of the transcendental meditation movement during the late 1960s and early 1970s,[2] whom Kosinski had met at the local TM Center in Cambridge, Massachusetts, and who embodied the calm and simple manner of Chauncy Gardiner.[3] The Cambridge TM Center was for years located at the corner of Chauncy and Garden Streets.

A film based on the book was made in 1979; Kosinski co-wrote the film's screenplay with Robert C. Jones.

Being There was published on April 21, 1971 and a film about the book was made in 1979.
