SPOILER ALERT: This story discusses plot elements from “The Fall Guy,” now playing in theaters. Long before Taylor Swift embarked on the Eras Tour, director David Leitch and producer Kelly McCormick had the idea to use “All Too Well” as a key moment in “The Fall Guy.” McCormick, a self-professed Swiftie, and Leitch were trying to find a fresh and contemporary song to fit into a particular scene. In the film, Ryan Gosling plays Colt Seavers, one of Hollywood’s top stuntmen. After experiencing an on-set accident, he falls off the grid for 18 months, ghosting aspiring director Jody (Emily Blunt), someone he also happens to be dating.
