Christopher Plummer, the acclaimed stage and film star, brought both charm and an air of menace to a vast range of roles from King Lear to a Klingon villain. At age 82, he added an Oscar win for “Beginners” to a shelf of trophies that already included two Tony Awards. But Mr. Plummer will always be remembered for the one part that he professed to hate but that made him a household name: the von Trapp patriarch in “The Sound of Music.”

Mr. Plummer, who was 91, died Feb. 5 at his home in Weston, Conn. The cause was complications from a fall, said his wife, Elaine Taylor Plummer.

Since coming of age in his native Canada, Mr. Plummer saw his career propelled by his dashing matinee idol looks and his forceful characterizations of Shakespearean and other classical roles.

A major stage draw for half a century, he returned through the years to the boards of Broadway, London’s West End and the two Stratfords — England and Ontario — and shifted with ease between parts created by such disparate writers as Neil Simon and Harold Pinter.

He made a dazzling impression as Iago to James Earl Jones’s moor in “Othello” in a 1982 Broadway staging of the Shakespeare tragedy. Writing in the New York Times, theater critic Walter Kerr called Mr. Plummer’s portrayal “quite possibly the best single Shakespearean performance to have originated on this continent in our time.”

The actor conveyed the extraordinarily nimble mind of the schemer Iago with a darting physicality. “The fatigue of the man is translated into the incessant activity of the man; when the repose is impossible, one must race forward to ruin,” Kerr added. “The concept is brilliant, the execution of it perfect.”

He won a Tony in the title role in a 1973 musical version of Edmond Rostand’s play “Cyrano de Bergerac.” His second Tony came in 1997 when he played his lifelong stage hero, John Barrymore, the once-great Shakespearean stage actor who drank himself to death.

Mr. Plummer’s dramatic gift was to imbue his performances with a measure of peril, said Antoni Cimolino, artistic director of the Stratford Festival theater in Ontario. “There is a sense of unpredictability which is the heart of theater,” he said. “And that sense of danger gave him so much power, both as a villain and also as a leading man.”

For all his stage renown — he earned seven Tony nominations — it was his casting in “The Sound of Music” that launched him to stardom. He had taken the role, he later said, because he wanted to try his hand at a musical.

“I thought that was gonna be it — it’s a little film that might enjoy a certain success,” he told London’s Daily Telegraph. “And then it would go away and I would know how to sing.”

The 1965 Hollywood adaptation of the Rodgers and Hammerstein musical co-starred Julie Andrews as the ingenue governess of the seven warbling von Trapp children. Mr. Plummer played the brood’s stern and widowed father, a retired Austrian naval officer named Captain Georg von Trapp.

The film won five Academy Awards, including best picture, and remains one of the most popular movies ever made, a television evergreen in nearly every corner of the world. To Mr. Plummer, it was “so awful, and sentimental and gooey,” and he winced every time he recalled crooning “Edelweiss” as a single tear ran down his cheek.

His disdain for the movie — which he variously liked to call “S&M” or “The Sound of Mucus” — was widely shared by critics for its banality amid the Nazi rise. For Mr. Plummer, the film paved the way for a screen stature that would support a lavish lifestyle and a freedom to take stage roles he wanted.

In all, he appeared in more than 200 movies and TV dramas, some artistic, some wildly popular, and some eminently forgettable.

Among his more memorable performances, he was a cunning and ambitious archbishop in “The Thorn Birds” (1983), the ABC ratings smash. He was a young Rudyard Kipling in “The Man Who Would Be King” (1975) and adroitly captured the mannerisms and nuances of “60 Minutes” correspondent Mike Wallace in “The Insider” (1999), about a tobacco company whistleblower (played by Russell Crowe). In the Oscar-winning “A Beautiful Mind” (2001), he was a psychiatrist who treats the schizophrenia of future Nobel laureate John F. Nash Jr. (also played by Crowe).

In the 1991 movie “Star Trek VI: The Undiscovered Country,” he played the Klingon general Chang, a nefarious character who enjoys spouting Shakespeare. He later had roles in films such as “Wolf” (1994), “12 Monkeys” (1995), “Syriana” (2005), “The Imaginarium of Doctor Parnassus” (2009), the animated “Up” (2009) and “Knives Out” (2019), playing a mystery writer who appears to have been murdered by a member of his family. He was nominated for an Emmy for playing a supporting part as Boston’s Cardinal Bernard Law, mired in scandal, in the TV film “Our Fathers” (2005).

He received an Oscar nomination for his supporting role as Russian novelist Leo Tolstoy in “The Last Station” (2009) and an Academy Award win for his supporting role in “Beginners” (2010), a romantic comedy, playing a terminally ill paterfamilias who announces he is gay.

Accepting his Oscar, the octogenarian turned to the statuette and declaimed, “Where have you been all my life?” The prize made him the oldest actor to win an Oscar, but his career was by no means over.

In 2018, at the age of 88, he received another Oscar nomination for best supporting actor for his portrayal of the oil tycoon J. Paul Getty in Ridley Scott’s “All the Money in the World.” Mr. Plummer became the oldest actor ever nominated. The circumstances surrounding his role gripped Hollywood. Just six weeks before the film’s scheduled release, sexual abuse allegations against Kevin Spacey, who had originally shot the part, prompted Scott to expunge Spacey from the movie and replace him with Mr. Plummer.

Mr. Plummer told an interviewer that in “about three days I had to say yes to the script, pack, get to London and do the stuff immediately.” His performance as the tightfisted grandfather of the kidnapped John Paul Getty III also gained him a best supporting actor nomination for the Golden Globe and Bafta awards.

“The nice part about awards and being nominated is the fact it wakes everybody up again, and makes them realize you’re alive and kicking and available,” he told the Times.

A love of literature

Arthur Christopher Orme Plummer was born in Toronto on Dec. 13, 1929. An only child, he was a toddler when his parents divorced, and it would not be until his late teens that he saw his father again. Meanwhile, Mr. Plummer moved with his mother to live with his grandfather and maiden aunts in Montreal.

His mother’s family was of patrician and cultured stock — a forebear was John Abbott, a former railroad president and Canada’s first native-born prime minister. His upbringing in an atmosphere of faded grandeur proved formative to Mr. Plummer’s life and career.

“Several nights a week we would indulge in that quaint but delightful Victorian diversion — we read aloud to each other after dinner,” he wrote in his 2008 memoir, “In Spite of Myself.” The reciting helped instill in him a love of literature and language that became the hallmark of his theatrical work.

After learning the ropes and much of the stage canon in radio drama and theater repertory, he was plucked for major dramatic roles while still in his mid-20s opposite such formidable actresses as Eva Le Gallienne, Katharine Cornell and Judith Anderson.

His first appearance at Ontario’s Stratford Festival, which would become a theatrical home over his career, was as Henry V in 1956. He won praise from New York Times theater critic Brooks Atkinson, who wrote that Mr. Plummer “plays Henry magnificently not only because he has the voice, skill and range, but also because he has the grace not to exploit a heroic role.”

In his dozen later seasons at the festival, he played the title roles in Shakespeare’s “Hamlet,” “King Lear,” “Antony and Cleopatra” and “Macbeth.”

Mr. Plummer said he grew cocky fast, turning down prestige movie work offered by the Hollywood mogul David O. Selznick in the late 1950s in favor of an offer to play Hamlet in Ontario “for 25 bucks a week. But at least it was Hamlet.” He added in his memoir that he “still harbored the old-fashioned stage actor’s snobbism toward moviemaking.”

As it happened, Mr. Plummer’s initial forays into film were less than auspicious. He debuted in director Sidney Lumet’s “Stage Struck” (1958) and that same year appeared in a drama called “Wind Across the Everglades” that quickly sank into obscurity. Six years passed before his next screen part, as the emperor Commodus in the all-star epic “The Fall of the Roman Empire.” That was quickly followed by “The Sound of Music.”

Having already rejected the allure of a studio contract for stage work, Mr. Plummer moved to England in the early 1960s to take roles in the heady, formative years of the Royal Shakespeare Company, playing Richard III, Benedick in “Much Ado About Nothing” and King Henry in Jean Anouilh’s “Becket.”

His demanding career and frequent all-night carousing with Peter O’Toole, Richard Harris and other legendarily bibulous actors took a costly toll on his personal life.

“I was a lousy husband and an even worse father,” he wrote, singling out his absenteeism from his first wife, singer and actress Tammy Grimes, and their daughter, Amanda Plummer, who became a Tony-winning actress.

Mr. Plummer found the party scene of the Swinging Sixties a good fit, where he also discovered romance in the form of one of the scene’s professional participants: Patricia Lewis, a showbiz columnist for a London newspaper.

One evening, sufficiently lubricated, they left their regular night spot with Lewis at the wheel. She crashed the convertible near Buckingham Palace in a smash that left Mr. Plummer unscathed but Lewis in a life-threatening coma. After her recovery, they wed in 1962 and divorced almost five years later.

Mr. Plummer found the anchor for his personal life in 1968, ironically, while shooting a period sex comedy called “Lock Up Your Daughters!”

The film bombed but one of the cast members, Elaine Taylor, would become his abiding partner, consenting to marry but only if he cleaned up his act. He agreed to give up the hard liquor and settle down. “I was just about to go down with the ship when, to the rescue came . . . a graceful angel,” he wrote in his memoir.

Survivors include his wife and daughter.

Mr. Plummer long ago abandoned his near-exclusive devotion to the stage for the richer pickings of New York and Hollywood, but he returned periodically to his acting roots to remind critics of his lacerating power in taxing roles such as Iago or Lear.

In his 60s, Mr. Plummer developed a one-man show of readings from the literature that shaped his life and work. “A Word or Two” took from sources such as the Old Testament and “Winnie the Pooh,” though Shakespeare loomed large as well.

A life spent mostly in the theater, he wrote, “taught me above all that there is no such thing as perfection — that in the arts there are no rules, no restrictions, no limits — only infinity.”
