Early life
Isaacs was born to Jewish parents in Liverpool on 6 June 1963. His father was a jeweller. He has two older brothers and one younger brother. He spent his earliest childhood years in the Liverpool suburb of Childwall, in a "closely knit & integrated" Jewish community co-founded by his Eastern European Jewish great-grandparents. He has said that being Jewish played a big role in his childhood, as he attended youth club in the local synagogue of King David High School in Liverpool's Childwall district, as well as a cheder twice a week as a young adult. When he was 11, he moved with his family to Canons Park, London and attended the Haberdashers' Aske's Boys' School in nearby Elstree at the same time as David Baddiel, Sacha Baron Cohen, Mark Kermode, and Matt Lucas. He describes the bullying and intolerance he observed and experienced during his childhood as "preparation" for portraying the "unattractive" villains he has most often played.
As a Jewish teen in London, Isaacs endured antisemitism by the National Front, a far-right extremist political party. His parents eventually immigrated to Israel. He later told an interviewer, "There were constantly people beating us up or smashing windows. If you were ever, say, on a Jewish holiday, identifiably Jewish, there was lots of violence around. But particularly when I was 16, in 1979, the National Front were really taking hold, there were leaflets at school, and Sieg Heiling and people goose-stepping down the road and coming after us." Following in the footsteps of his three brothers (one who became a doctor, one a lawyer, and one an accountant), he studied law at Bristol University from 1982 to 1985, becoming involved in the university's theatre club there; he eventually acted in over 30 plays and performed each summer at the Edinburgh Festival Fringe, first with Bristol University and then twice with the National Student Theatre Company. After graduating, he went immediately to train at London's Central School of Speech and Drama from 1985 to 1988.
Early work
After training as an actor, Isaacs immediately began appearing on the stage and on television; his film debut was in a minor role as a doctor in Mel Smith's The Tall Guy (1989). He was initially known as a television actor, with starring roles in the ITV drama Capital City (1989) and the BBC drama Civvies (1992) and guest roles in series such as Taggart, Inspector Morse and Highlander: The Series (1993). He also played Michael Ryan in ITV's adaptation of Martina Cole's novel Dangerous Lady, directed by Jack Woods and produced by Lavinia Warner in 1995.
On stage, he portrayed the "emotionally waffling" gay Jewish office temp Louis Ironson in Tony Kushner's Pulitzer-Prize-winning Angels in America: A Gay Fantasia on National Themes, at the Royal National Theatre, in its London première, performing the role in both parts, Part One: Millennium Approaches, in 1992, and Part Two: Perestroika, in 1993. When auditioning for the role, he told the producers, "Look, I play all these tough guys and thugs and strong, complex characters. In real life, I am a cringing, neurotic Jewish mess. Can't I for once play that on stage?"
After appearing in Dragonheart (1996), Isaacs landed his first major Hollywood feature-film role alongside Laurence Fishburne in the horror film Event Horizon (1997) where he played the role of D.J., the doctor of Lewis and Clark. Subsequently, he appeared in the Bruce Willis blockbuster Armageddon (1998). Initially called upon to take a fairly substantial role, Isaacs was eventually cast in a much smaller capacity as a planet-saving scientist so that he could accommodate his commitment to Divorcing Jack (1998), a comedy-thriller he was making with David Thewlis. Isaacs played a charismatic honourable priest opposite Kirstie Alley in the miniseries The Last Don II (1998). After that he portrayed a priest opposite Julianne Moore and Ralph Fiennes in Neil Jordan's adaptation of Graham Greene's The End of the Affair (1999).
2000s
In 2000, Isaacs appeared in the historical epic film The Patriot, opposite Mel Gibson and Heath Ledger, playing the ill-fated sadistic cavalry officer Colonel William Tavington. Critics deemed the performance "memorable"; a Moviefone article called it "his biggest international break to date". It led to rumours that Isaacs would be nominated for the Academy Award for Best Supporting Actor at the 73rd Academy Awards. Nonetheless, demonstrating his range beyond historic films, Isaacs next chose to play a drag queen in the romantic comedy-drama Sweet November (2001).
Isaacs has appeared in many other films, most notably as Lucius Malfoy in the Harry Potter series (2002–2011). Of the Harry Potter books by J. K. Rowling, he has said: "I went off and read the books after the audition and I read the first four books in one sitting—you know—didn't wash, didn't eat, drove around with them on the steering wheel like a lunatic. I suddenly understood why my friends, who I'd thought were slightly backward, had been so addicted to these children's books. They're like crack."
In "The Naked and the Dead", an article published in the San Francisco Chronicle on 26 November 2006, Neva Chonin named the character Lucius Malfoy one of the 12 "Sexiest Men Who Were Never Alive" and Isaacs one of the 13 "Sexiest Men Who Are Real and Alive".
Before making the film, when asked whether or not he would be in Harry Potter and the Order of the Phoenix (2007), Isaacs replied, "I hope so – you'll have to ask David [producer David Heyman]. I can't bear the idea that somebody else would get to wear my Paris Hilton wig, but you never know." Isaacs also talked to Rowling on the…
