First Monday in October (film)

First Monday in October is a 1981 American film based on the play of the same name by Jerome Lawrence and Robert E. Lee, and directed by Ronald Neame. Walter Matthau for which he was nominated for a Golden Globe Award for Best Actor Motion Picture Musical or Comedy and Jill Clayburgh for which she was nominated for a Golden Globe Award for Best Actress Motion Picture Musical or Comedy performed the principal roles.

At the start of the story, the death of Associate Justice Stanley Moorehead has created a vacancy on the United States Supreme Court. The new appointee turns out to be Ruth Loomis, a staunch conservative, who is confirmed as the first female US Supreme Court Justice. She and Associate Justice Daniel Snow, a committed liberal and many years older than Loomis, clash intellectually on just about every judicial issue before them. One case involves a pornographic film and arguments about freedom of speech. With time, the two characters develop a liking and respect for each other.
