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

Context: Being There is a satirical novel by the Polish-born writer Jerzy Kosinski, published April 21, 1971. 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, whom Kosinski had met at the local TM Center in Cambridge, Massachusetts, and who embodied the calm and simple manner of Chauncy Gardiner. 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.

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