Director Jerry Paris, best known for directing The Dick Van Dyke Show , treats the material like a protracted sitcom. The film never quite decides if it wants to be a slapstick comedy, a satire of American jingoism, or a buddy movie between Max and his American captors. It’s that tonal wobble that likely killed it in 1969. Viva Max! was released on July 23, 1969 — four days after the moon landing. But the bigger problem was the cultural mood. The Tet Offensive was a recent memory. The nation was polarized over Vietnam. The last thing a war-weary, flag-pin public wanted to watch was a comedy that suggested the Alamo—a sacred site of Texan martyrdom—was actually a silly piece of real estate worth surrendering for a pair of boots.

The supporting cast is a time capsule of 1960s character actors. Jonathan Winters plays a fast-talking, cynical general with a crew cut. John Astin (fresh off The Addams Family ) is a manic press agent. And in a small, sweaty role as a Texas governor, a young character actor named John Hillerman steals every scene.

The answer, according to the film’s box office receipts: audiences would rather watch Neil Armstrong take one small step than watch Peter Ustinov take one very silly one.
