NEW YORK (REUTERS) - Harold "Hal" Prince, who won a record 21 Tony Awards as producer and director of some of Broadway's biggest hits of the second half of the 20th century including The Phantom Of The Opera, West Side Story, Fiddler On The Roof, Cabaret and Evita, died on Wednesday (July 31) at age 91.

Prince died after a brief illness in Reykjavik, Iceland, his publicist said.

Prince was famed for his dynamic collaborations with two composers, American Stephen Sondheim and Briton Andrew Lloyd Webber and had been a protege of legendary Broadway showman George Abbott.

Prince became a wunderkind producer in the 1950s with hits including West Side Story, the groundbreaking re-imagining of Shakespeare's Romeo And Juliet.

He turned to directing in the 1960s with hits including Cabaret, set in decadent Berlin amid the rise of the Nazis, for which he won the first of eight Tonys as best director.

He joined with Sondheim to create a series of sophisticated musicals in the 1970s, then teamed with Lloyd Webber for the blockbusters Evita and The Phantom Of The Opera, which became the longest-running show in Broadway history.

"He's the best director of musicals around by far,"Sondheim, whose work with Prince included the 1970s musicalsCompany, Follies, A Little Night Music, Pacific Overtures and Sweeney Todd, said in a 1984 interview with Prince biographer Carol Ilson.

"He has a more acute ear than most producers. He takes it seriously and is more daring, imaginative and endlessly creative. He likes to take chances," Sondheim said.

In 1979, Prince directed two huge hits that opened within months of each other on Broadway. In March, Sweeney Todd - the macabre tale of a murderous barber set to Sondheim's music - made its debut. In September, Prince brought Evita to New York from London, where it had opened the previous year, telling the story of Eva Peron, the magnetic wife of Argentine strongman Juan Peron, with Lloyd Webber's music.

Prince rebounded from a handful of 1980s misfires with his biggest hit. The Phantom Of The Opera - the story of a disfigured musical genius obsessed with a young operatic soprano - opened in London in 1986, then took Broadway by storm in 1988.

"There is not a single scene in the show that does not have a surprise in it," Prince told Playbill in 2011 of Phantom.

"Sometimes, it's fire that you don't know is going to be there, sometimes it's a voice, sometimes it's a piano playing by itself, but there's always something. And sometimes it's a piece of scenery almost falling on a diva," Prince said.

'I WOULDN'T HAVE A CAREER'

Prince, who sported a neatly trimmed white beard, balding head and dark-rimmed glasses usually perched precariously high on his forehead, hung a bulletin board in his Rockefeller Centre office in New York adorned with notes he wrote to himself. One seemed to underscore his willingness to take risks: "I wouldn't have a career if I'd taken a lot of advice."

He generally eschewed the time-tested Broadway practice of casting stars to carry a musical. As a director, he pioneered the "concept musical" with Sondheim, with shows presenting themes in place of a narrative plot. Follies, for example, used a reunion of chorus girls to explore growing older.

Prince was born in New York on Jan 30, 1928. His parents divorced when he was young and he was raised by his mother and stepfather, a stockbroker. His family frequented the theatre, and he was dazzled at age eight by a performance by Orson Welles.

"I really was interested in theater from the get-go and that's very lucky... I caught up with a few musicals but they always struck me as kind of silly - which is why, I suppose, so few of the musicals I've done have been appropriately silly," Prince said in a 2007 interview with the Academy of Achievement.

After an Ivy League education at the University of Pennsylvania, Prince landed a job as an assistant to Abbott but was drafted into the US Army in 1950 and sent to West Germany.

He returned to Abbott two years later.

Along with Robert Griffith, another Abbott assistant, Prince decided to try his hand as a producer. At age 26, he opened The Pajama Game in 1954. The peppy show about romance in a pajama factory was a hit and won the Tony Award as best musical.

In 1955, they opened their second show, Damn Yankees, a tale of a baseball fan who sells his soul to the devil to help his favourite team win. It also won a Tony as best musical.

Prince and Griffith produced 1957's West Side Story, a love story set among gangs in contemporary New York City and put to music by Leonard Bernstein. It became one of the most influential musicals in Broadway history.

Prince produced shows on his own after Griffith's death in 1961. He had hits with two shows starring Zero Mostel. A Funny Thing Happened On The Way To The Forum, opening in 1962, was a musical romp sent in ancient Rome. Fiddler On The Roof, about Jewish villagers in early 20th century Russia, opened in 1964 and became the longest-running show in Broadway history to date.

In 1966, he produced and directed Cabaret, energised by a leering, electric performance by Joel Grey. In 1993, he directed Kiss Of The Spider Woman, featuring Chita Rivera, who had appeared 36 years earlier in West Side Story.

Prince also was in demand as an opera director. He twice directed films, but neither Something For Everyone (1970) with Angela Lansbury nor the film version of A Little Night Music (1977) with Elizabeth Taylor became a success.

Prince was active well into his 80s including directing Bernstein's Candide in 2017.

Prince is survived by his two children and his wife of 56 years, Judith Chaplin, the daughter of composer Saul Chaplin.
