Also innovative was the editing of the climactic action sequence, when Apache warriors attack the stagecoach. A fundamental law of film editing is the 180-degree rule: Although you can splice together a scene from diverse angles, you will confuse viewers if you cross an invisible 180-degree boundary, flipping the perspective so that a character who was facing left now faces right.
In the attack sequence, Spencer and Lovering repeatedly and deliberately broke that rule. As David Meuel observed in his book “Women Film Editors: Unseen Artists of American Cinema” (2016), “by disorienting and confusing the audience, it created a closer bond between viewers and the characters in the stagecoach, who are themselves thoroughly disoriented and confused. So, rather than compromising the cinematic experience, this deliberate breaking of the 180-degree rule actually intensified it.”
Spencer began working solo in 1941, and over the next decade she averaged two movies a year, working with notable directors like Hitchcock (“Lifeboat,” 1944), Elia Kazan (“A Tree Grows in Brooklyn,” 1945) and Ernst Lubitsch (five movies in which Spencer showed off her impeccable comic timing, including “To Be or Not to Be,” 1942).
She made most of those films as a staff editor at the 20th Century Fox studio, a job she took in 1943 and kept for the next 24 years. During her tenure, the Hollywood studio system collapsed and the aesthetics of editing evolved; for example, dissolving from one scene to another went out of style.
Spencer remained a constant, working with geniuses and journeymen, deferring to directors who had a vision in mind but offering creative flourishes when there were opportunities.
“When you work with a new director who has never had any editing experience, he often asks for the impossible,” she wrote in 1974. “You can’t tell him it won’t work. You just have to do it his way and let him realize that maybe he was wrong.”
In the soapy “Valley of the Dolls” (1967), directed by Mark Robson and based on Jacqueline Susann’s best seller about three young women struggling with the temptations of show business, she cut together some striking montages that nodded to the French New Wave. In one sequence, Patty Duke spits out water in the shower, does a multiple-exposure somersault, exercises on a rowing machine (with the top half and the bottom half of the screen deliberately out of sync) and gets married — a significant plot point, seen only in a black-and-white still photograph.
