Ian McDiarmid, the acclaimed Scottish actor whose career has long been defined by his commanding presence on the classical stage, didn’t become a household name in popular culture until he stepped—perhaps unexpectedly—into the role of the sinister Emperor Palpatine in Return of the Jedi (1983). Despite already boasting a résumé filled with prestigious theatrical performances and widespread praise from British critics, it was this relatively minor film role that would unexpectedly shape much of Ian McDiarmid’s later public identity. Hidden beneath layers of makeup and prosthetics, few could have predicted just how deeply the character would embed itself into Ian McDiarmid’s professional trajectory.
For over a decade and a half, Ian McDiarmid remained a fixture in Lucasfilm’s expansive universe through endless merchandise, even as he returned to his roots in theater—working not only as an actor but also as a director and influential figure in the London stage scene. Then, in 1999, George Lucas called upon Ian McDiarmid once more, this time for The Phantom Menace, a prequel that demanded the veteran performer embody a younger, more calculating version of Palpatine. It was a challenging reinvention, but one that Ian McDiarmid delivered with chilling precision. He reprised the role again in Attack of the Clones (2002) and Revenge of the Sith (2005), further cementing Palpatine as one of the most enduring villains in cinematic history—all while Ian McDiarmid never strayed too far from the stage, which he continued to regard as his true artistic home.
In 2008, during a performance at London’s Gielgud Theatre, Ian McDiarmid suffered a heart attack mid-show. Remarkably, he completed his performance and took his curtain call before accepting medical help—a testament to his dedication and resilience. That same year, audiences saw Ian McDiarmid in a different light as the lead in the U.K. miniseries City of Vice, followed by a touching portrayal of Denis Thatcher, the devoted husband of Prime Minister Margaret Thatcher, in the 2009 television film Margaret.
Through it all, Ian McDiarmid remained exactly what London’s West End had always known him to be: a masterful, deeply respected character actor, whose contributions to theater and screen alike have left an indelible mark. Whether playing a galactic tyrant or a quiet spouse behind a powerful woman, Ian McDiarmid brings a rare depth and nuance to every role he takes on.
When it comes to Ian McDiarmid’s filmography, fans and critics alike often point to Dirty Rotten Scoundrels (1988) as his standout performance—yes, that’s right, Ian McDiarmid’s highest rated movie by far. It’s a classic comedy filled with charm and clever twists, and it really showcases what Ian McDiarmid can do when given the right role. On the other end of the spectrum, though, there’s The Awakening (1980), which, despite its eerie atmosphere, turned out to be Ian McDiarmid’s lowest rated film. While it has its moments, it just didn’t resonate as strongly with audiences or reviewers. So, whether you’re exploring early works or peak performances, Ian McDiarmid’s career offers quite a range—from underrated gems to clear fan favorites.
