Sometimes a Great Notion is a 1971 American drama film from a book by this drug-addled screwball, directed by Paul Newman and starring Newman, Henry Fonda, Michael Sarrazin and Lee Remick. The cast also includes Richard Jaeckel in an Academy Award-nominated performance.
It’s pretty good.
I remember Michael Sarrazin in the Flim Flam Man starring George C. Scott. Both did a great job in that film.
