High Noon unfolds in real time — the running time of the story closely parallels the running time of the film itself. Producer Stanley Kramer said that the filmmakers hoped this would “create a sense of urgency as the noon hour approached.” Director Fred Zinnemann wrote the word CLOCK next to many scenes in his script, and he prepared a list of inserts in which clocks would be prominently visible:

Scene 36 — Marshal’s Office — Clock 10:40 a.m.
Scene 60 — Marshal’s Office — Clock 10:51 a.m.
Scene 76 — Helen’s Room — Clock 10:55 a.m.
Scene 86 — Marshal’s Office — Clock 11:02 a.m.
Scene 96 — Helen’s Room — Clock 11:05 a.m.
Scene 101 — Marshal’s Office — Clock 11:07 a.m.
Scene 130 — Saloon — Clock 11:19 a.m.
Scene 144 — Mart Howe’s House — Clock 11:26 a.m.
Scene 231 — Saloon — Clock 11:44 a.m.
Scene 256 — Hotel Lobby — Clock 11:50 a.m.
Scene 303 — Saloon — Clock 11:59 a.m.
Scene 312 — Saloon — Clock 12:00 p.m.

An insert for Scene 294 was never shot — it would have started on a pendulum and panned up to show a clock with no hands, superimposed on a closeup of Gary Cooper’s Will Kane. Zinnemann said he’d got the idea from a handless clock he’d seen in front of a funeral home on Sunset Boulevard. He said it “would have intensified the feeling of panic.”

Recognize this locomotive? You’ve almost certainly seen it before: Built in 1891, “Sierra No. 3” was adopted by Hollywood in 1948 and became “the most photographed locomotive in the world,” appearing in The Red Glove, The Terror, The Virginian, The Texan, Young Tom Edison, Sierra Passage, Wyoming Mail, High Noon, The Cimarron Kid, Kansas Pacific, The Moonlighter, Apache, Rage at Dawn, The Return of Jack Slade, Texas Lady, The Big Land, Terror in a Texas Town, Man of the West, Face of a Fugitive, The Outrage, The Rare Breed, The Great Race, The Perils of Pauline, Finian’s Rainbow, A Man Called Gannon, The Great Bank Robbery, Joe Hill, The Great Northfield Minnesota Raid, Oklahoma Crude, Nickleodeon, Bound for Glory, The Apple Dumpling Gang Rides Again, The Long Riders, Pale Rider, Blood Red, Back to the Future Part III, Unforgiven, and Bad Girls.

Gary Cooper alone starred in four movies with it, including High Noon; Clint Eastwood, who appeared with it in Rawhide, Pale Rider, and Unforgiven, said it was “like a treasured old friend.” TV shows:

The Lone Ranger, Tales of Wells Fargo, Casey Jones, Rawhide, Overland Trail, Lassie, Death Valley Days, The Raiders, Petticoat Junction, The Wild Wild West, The Big Valley, The Legend of Jesse James, Scalplock, Iron Horse, Cimarron Strip, Dundee and the Culhane, The Man From U.N.C.L.E., Ballad of the Iron Horse, Gunsmoke, Bonanza, The Great Man’s Whiskers, Inventing of America, Little House on the Prairie, Law of the Land, A Woman Called Moses, Lacy and the Mississippi Queen, Kate Bliss and the Ticker Tape Kid, The Night Rider, The Last Ride of the Dalton Gang, Belle Starr, East of Eden, Father Murphy, The A-Team, Bonanza: The Next Generation, The Adventures of Brisco County, Jr., and Doctor Quinn, Medicine Woman.

William L. Withhuhn, former transportation history curator at the Smithsonian Institution, wrote, “Sierra Railway No. 3 has appeared in more motion pictures, documentaries, and television productions than any other locomotive. It is undisputedly the image of the archetypal steam locomotive that propelled the USA from the 19th century into the 20th.”

Chess boxing has evolved from a performance art piece to a serious worldwide professional sport. Two competitors engage in six rounds of chess and five rounds of boxing, switching between the two every three minutes. A player can win by knockout, technical knockout, or checkmate, or if his opponent resigns, exceeds the time limit, or is disqualified. If both the contests end in a draw, the player of the black pieces wins.

In football tennis (below), you have to return the ball over the net without using your hands. Up to three players can play on each side, with corresponding rules regarding the number of touches and bounces allowed on each return. This sport is growing too — the first rules were written in 1940, and it held its 11th world championship in 2014. Now we need a way to combine all four of these.

Alfred Hitchcock’s 1945 film Spellbound was shot in black and white, but the conclusion contains two frames of red when a gun is fired (1:54:40 above).
