In 2018, Disney released the much-awaited spinoff in the Star Wars universe: Solo: A Star Wars Story, based on the character made iconic by Harrison Ford. Despite a blockbuster production and marketing budget, the film went on to severely underperform at the box office. Trade pundits had their favorite theories why this happened, but perhaps the most telling explanation came from Ron Howard, the movie's director. In an interview with Josh Horowitz, the very first reason he attributed the failure to was it's Memorial Day release date. Strategy for theatrical releases of movies encompass several factors, but perhaps none so deliberated upon as the release date. Will the movie clash with a feature in a similar genre? Will a summer release date bode better than a December release? Are all long weekends equal? Hollywood has an abundance of stories where a movie's poor performance is attributed to an ill-chosen release date. In this talk, I try to find the answers by examining patterns in release-date strategy. As we shall see, the results don't always align with conventional wisdom, and that differing factors can make an otherwise excellent choice, an extremely poor one.
