James Elmo Williams (April 30, 1913 – November 25, 2015) was an American film and television editor, producer, director and executive.

Williams was involved in the production of The Longest Day (1962) and Cleopatra (1963),[4] and he was a producer of the film Tora!

Williams edited the film Design for Death (1947), which won an Academy Award for Best Documentary Feature.

Williams won the Academy Award for Best Film Editing for his work on 1952's High Noon (directed by Fred Zinnemann and co-edited with Harry W. Gerstad, although he was subordinate to Gerstad), and was nominated again for 1954's 20,000 Leagues Under the Sea (directed by Richard Fleischer).

Critic James Berardinelli wrote, "High Noon's tension comes through Kane's desperation, aided in no small part by Elmo Williams' brilliant editing as the clock ticks down to twelve.

"[6] In his memoir, Williams states that this well-known montage was specifically edited to match the music composed for the scene by Dimitri Tiomkin.

Lorraine wrote the lyrics to the theme song for the movie Those Magnificent Men in Their Flying Machines (1965); British composer Ron Goodwin set them to music and conducted.
