Isaacs was born toJewish parents inLiverpool on 6 June 1963.[6] His father was a jeweller.[7] He has two older brothers and one younger brother.[6] He spent his earliest childhood years in the Liverpool suburb ofChildwall, in a "closely knit & integrated" Jewish community co-founded by hisEastern European Jewish great-grandparents.[8] He has said that being Jewish played a big role in his childhood, as he attended youth club in the localsynagogue ofKing David High School in Liverpool'sChildwall district, as well as acheder twice a week as a young adult.[9][10][11] When he was 11, he moved with his family toLondon and attended theHaberdashers' Aske's Boys' School in nearbyElstree at the same time asDavid Baddiel,Sacha Baron Cohen,Mark Kermode, andMatt Lucas.[9] 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.[3][9]
As a Jewish teen in London, Isaacs enduredantisemitism by theNational Front, afar-right extremist organisation. His parents eventuallyemigrated to Israel.[9] 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, andSieg Heiling and peoplegoose-stepping down the road and coming after us."[7] Following in the footsteps of his three brothers (one who became a doctor, one a lawyer, and one an accountant),[6] he studied law atBristol 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 theEdinburgh Festival Fringe, first with Bristol University and then twice with the National Student Theatre Company. After graduating, he went immediately to train at London'sCentral School of Speech and Drama from 1985 to 1988.[3][6][12]
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 inMel Smith'sThe Tall Guy (1989).[12] He was initially known as a television actor, with starring roles in the ITV dramaCapital City (1989) and the BBC dramaCivvies (1992) and guest roles in series such asTaggart,Inspector Morse andHighlander: The Series (1993).[12] He also played Michael Ryan in ITV's adaptation ofMartina Cole's novelDangerous Lady, directed by Jack Woods and produced byLavinia Warner in 1995.[13]
On stage, he portrayed the "emotionally waffling"[12] gay Jewish office temp Louis Ironson in Tony Kushner's Pulitzer-Prize-winningAngels in America: A Gay Fantasia on National Themes, at theRoyal National Theatre, in its London première, performing the role in both parts,Part One: Millennium Approaches, in 1992, andPart Two: Perestroika, in 1993.[2] When auditioning for that 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?"[10]
After appearing inDragonheart (1996), Isaacs landed his first major Hollywood feature-film role alongsideLaurence Fishburne in the horror filmEvent Horizon (1997) where he played the role of D.J., the doctor of Lewis and Clark. Subsequently, he appeared in theBruce Willis blockbusterArmageddon (1998).[12] 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 toDivorcing Jack (1998), a comedy-thriller he was making withDavid Thewlis.[6] Isaacs played a charismatic honourable priest oppositeKirstie Alley in the miniseriesThe Last Don II (1998).[14] Following that he portrayed a priest oppositeJulianne Moore andRalph Fiennes inNeil Jordan's acclaimed adaptation ofGraham Greene'sThe End of the Affair (1999).
Isaacs has appeared in many other films, most notably asLucius Malfoy in theHarry Potter series of films (2002–2011). Regarding the Harry Potter books byJ. 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 likecrack." (From an interview in 2009 on ITV'sThe Justin Lee Collins Show)[16]
In "The Naked and the Dead", an article published in theSan 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".[17]
Prior to the making of the film, when asked whether or not he would be inHarry Potter and the Order of the Phoenix (2007), Isaacs replied, "I hope so – you'll have to ask David (producerDavid Heyman). I can't bear the idea that somebody else would get to wear myParis Hilton wig, but you never know."[18] Isaacs also talked to Rowling on the inclusion of Lucius Malfoy in the then unpublishedHarry Potter and the Deathly Hallows, so that he would have a part in the seventh and final film: "The character does not appear in the sixth book,Harry Potter and the Half-Blood Prince; but ... [Isaacs joked], 'I fell to my knees and begged ... It didn't do any good. I'm sure she doesn't need plot ideas from me. But I made my point. We'll see. Like everybody else, I'm holding my breath to July to see what's in there. I just want to bust out of prison, that's all. I don't want to stay inAzkaban most of my life.' "[19] Ultimately Isaacs did reprise the role of Malfoy as acameo appearance inHarry Potter and the Half-Blood Prince (2009), where he is seen in a movingportrait. Afterwards, Isaacs reprised the role again inHarry Potter and the Deathly Hallows – Part 1 (2010) andPart 2 (2011).[20]
On television, he also portrayed actorHarry H. Corbett inThe Curse of Steptoe, part of "a season of newone-off dramas forBBC Four revealing the stories behind some of Britain's best loved television entertainers, and their achievements", first broadcast in March 2008.[23][24] On American television, Isaacs appeared in three episodes ofThe West Wing in 2004, prior to developing his most notable TV serial role, as Michael Caffee inBrotherhood (2006–08).

This tribute to Harold Pinter co-sponsored by the Martin E. Segal Theatre Center (MESTC), ofThe Graduate Center of TheCity University of New York (CUNY), was part of the Fifth AnnualPEN World Voices Festival of International Literature, held in New York City, from 27 April to 3 May 2009.[33][34]
Isaacs starred as Detective Michael Britten in the NBC police procedural fantasy drama seriesAwake, which premiered on 1 March 2012, and ended in May 2012. After Britten gets into a terrible car wreck with his family, his dreams begin to take on two alternate realities, one in which his wife died in the crash and one in which his son died. Says Isaacs about the ambitious premise: "There's no question it's challenging. We've got a bunch of very experienced writers who have written things from HBO shows toThe X-Files, to24 and everything in between. And they are challenged. All of them have said that it's the hardest job that they've ever had. But sometimes that's a good thing. If it comes easily, that they could write in their sleep, I personally wouldn't want to act – and I think the audience wouldn't want to watch."[35]
In 2015, Isaacs took the lead role in theUSA Network action adventure drama seriesDig. Isaacs plays an FBI agent (which was named Peter Connelly) stationed in Jerusalem who uncovers a 2,000-year-old conspiracy while investigating an archaeologist's murder.

In August 2020, Isaacs revealed that he had achieved sobriety after struggling with a drug and alcohol addiction for over two decades.[60] He traced his experience back to being 12 years old, when a bartender gave him and his friends a bottle ofSouthern Comfort, after which he "woke up with a splitting headache, stinking of puke with a huge scab and the memory of having utterly shamed [himself]".[60] He subsequently "chased the sheer ecstatic joy [he] felt that night for another 20 years with increasingly dire consequences".[60] He eventually realised he needed help, but asked fans onTwitter not to congratulate him on his sobriety as "pride is the worst part".[61]
