Sir Ian McKellen has paid tribute to his longtime friend and fellow actor Sir Patrick Stewart, remembering him as an outspoken, loyal and deeply passionate man whose Yorkshire roots remained central to his identity throughout his life.

Stewart, best known for playing Captain Jean-Luc Picard in Star Trek: The Next Generation and Professor Charles Xavier in the X-Men film franchise, died at his home in Los Angeles on Wednesday, October 28, aged 86.

His death was announced on Thursday, October 29, in a statement shared through his official social media accounts. His representative said he had experienced a brief period living with Alzheimer's disease and Lewy body dementia.

In a heartfelt tribute shared on October 29, McKellen reflected on their friendship, which began about five decades ago when both were young actors working with the Royal Shakespeare Company.

McKellen described Stewart as a proud Yorkshireman whose directness and honesty made him someone people could depend on.

He recalled that Stewart never concealed his feelings and was always willing to speak openly, even on difficult subjects.

One of McKellen's strongest memories involved a conversation in central London when Stewart told him he had received an offer to take a leading role in Star Trek.

McKellen remembered advising his friend to consider the possible impact on his British theatre career before accepting the opportunity.

Stewart eventually took the role, a decision that introduced him to millions of television viewers worldwide and established him as one of the most recognisable faces in science fiction.

Beyond Star Trek, he became internationally celebrated for portraying Professor Charles Xavier in the X-Men films. He also maintained a distinguished theatre career, performing works by Shakespeare, Henrik Ibsen, Arthur Miller and other acclaimed playwrights.

McKellen said Stewart successfully balanced his international fame with his commitment to classical theatre, appearing in productions in Stratford-upon-Avon, London's West End and Broadway.

Although the United States became his adopted home, Stewart remained closely connected to his birthplace. One of his most significant achievements, McKellen noted, was becoming Chancellor of the University of Huddersfield in Yorkshire.

Stewart's wife, Sunny Ozell, whom he married in 2013, was also remembered in McKellen's tribute for standing by the actor through the difficult periods of his life.

The announcement of Stewart's death has prompted tributes from colleagues across the entertainment industry.

His Star Trek colleague William Shatner remembered him as a remarkable performer who brought intelligence and humanity to his roles, while X-Men co-star Hugh Jackman described him as a great friend and mentor.

Marvel Studios also honoured Stewart, praising his portrayal of Professor Xavier and the lasting influence he had on audiences.

Stewart's final appearance in Avengers: Doomsday is expected to reach cinemas in December 2026, meaning audiences will have another opportunity to see him on screen after his death.

For McKellen, however, the loss goes beyond the departure of an internationally celebrated actor. It is the loss of a friend whose honesty, warmth and loyalty made him deeply loved.
