Being There (1979)
"(...) Jerzy Kosinski, assisted by award-winning screenwriter Robert C. Jones, adapted his 1971 novel for the screenplay which Hal Ashby directed with an understatement to match the subtlety and precision of Sellers’ Academy Award-nominated performance. (...) Film critic Robert Ebert said he admired the film for "having the guts to take this totally weird conceit and push it to its ultimate comic conclusion." That conclusion is a philosophically complex film that has remained fresh and relevant."
