Lucasfilm following the movie's release, Kazanjian took over the producer's reins for Return of the Jedi. Kurtz decided not to produce the latter film as he found its story to be too commercial, as well as redundant of the first film in the trilogy. The Empire Strikes Back was released on May 21, 1980, becoming the most critically acclaimed chapter in the Star Wars saga and one of the most highly rated films in history. It earned more than $538 million worldwide over the original run and several re-releases, making it highest-grossing film in 1980. When adjusted for inflation, it is the twelfth-highest-grossing film in the U.S. and Canada . In 2010, the film was selected for preservation in the National Film Registry by the Library of Congress for being "culturally, historically, and aesthetically significant." Productions post-Lucasfilm Kurtz claimed that he and George Lucas clashed over how to progress the Star Wars series. Kurtz claimed that after Raiders of the Lost Ark in 1981, Lucas became convinced that audiences no longer cared about the story and were simply there for thrills and entertainment, and began to deviate from the originally planned plotlines for Return of the Jedi, at which point Kurtz quit the series—though opposing sources state that he was fired by Lucas due to his mishandling of The Empire Strikes Back, which went massively overbudget and overschedule. Kurtz also claimed Lucas changed the emphasis from storytelling to prioritizing toy merchandising. In a 2010 interview for the L.A. Times, Kurtz revealed he had become disillusioned with what he saw as the commercially driven direction the franchise was taking, as well as the related changes that Lucas made to the plot of the third movie, which was originally much darker, and supposedly included the death of Han Solo. He stated that: I could see where things were headed. The toy business began to drive the empire. It's a shame. They make three times as much on toys as they do on films. It's natural to make decisions that protect the toy business but that's not the best thing for making quality films. Kurtz was particularly displeased with Lucas' decisions in Return of the Jedi to resurrect the Death Star and to change the plot outline from one that ended on a "bittersweet and poignant" note to one having a "euphoric ending where everyone was happy". Kurtz later expressed his dissatisfaction with
