John, who won an Oscar for his work, was a designer for the incredibly popular movies since they first hit cinemas back in 1977.
From Darth Vader to Princess Leia, John designed the iconic looks known and loved to this day.
He began working in movies as a military history expert, before working with legendary filmmaker Stanley Kubrick in 1975 on ‘Barry Lyndon’.
It was from then that he progressed to costume design, where he moved into designing for Star Wars.
He had never seen a science fiction movie prior to working on one of the most popular film franchises in the world.
He said: “Since I had just finished the work for Kubrick I thought I’d investigate and met George Lucas at Elstree Studios in Borehamwood.”

John won his second Oscar for his work on Richard Attenborough’s 1982 hit Gandhi.
