The film opened May 25, 1977, and Guinness’ stunned response to its reception was captured in his diary. On May 27: “Splendid news of reaction to Star Wars continues to come in.” On June 3: “Am pinning my hopes on Star Wars percentage which could bring me £100,000 or more if it does Jaws business, as predicted.”
The film exceeded Jaws‘ business, grossing over $300 million in its initial release — earning Guinness more than $7 million immediately ($33 million today) and an estimated $95 million by the time of his death in 2000 at 86. Despite that unheard-of salary for what amounted to 20 minutes of screen time, Guinness was reluctant to come back for a sequel.
Over lunch at Morton’s in 1979, Lucas asked him if he would consider returning for “a couple of days” of work on Star Wars II — later known as The Empire Strikes Back. One week later, Guinness wrote in his diary, “I said yes to a day’s work on Star Wars II … It’s dull rubbishy stuff but, seeing what I owe to George Lucas, I finally hadn’t had the heart to refuse.”
