When a bawdy and conniving Roman slave (Zero Mostel) realizes that his master's son pines for the beautiful young woman next door, he sees an opportunity to secure his freedom and works to secure a courtship between the two. After a prominent Roman soldier beats him to the punch and arranges to purchase the girl, he concocts a more outrageous plot. "A Funny Thing Happened on the Way to the Forum" is an amusing adaptation of Stephen Sondheim's musical and features his great raunchy songs, a hilarious performance from the inimitable Mostel, and funny supporting roles from Jack Gilford and the great Buster Keaton in what proved to be his final film.
