Lars Eidinger Might Be the Greatest German Actor You’ve Never Heard Of

The German actor Lars Eidinger could not have been more easygoing at the photo shoot for this article. After arriving sans entourage in front of the Plaza Hotel, he clambered up a couple of stacked N.Y.P.D. concrete barriers, precariously posing like a gigantic besuited stork. As the photographer eyed a gurgling fountain nearby, Eidinger casually asked: “I go in?”

It was a chilly, drizzly October afternoon in New York, but he took off his socks and shoes, pulled up his pants and waded into the water. Afterward, he stripped down to his underwear and changed into the sweats he’d brought along (just in case), unfazed by gusts of wind and gawkers on the street.

That go-with-the-flow spontaneity won’t come as a surprise to anybody who’s seen Eidinger onstage. His Richard III at the Brooklyn Academy of Music in 2017, for example, was a chaotic-evil rock ’n’ roll goblin, the performance simultaneously illuminating and unhinged. This monarch was “a bogeyman guaranteed to haunt your nightmares for weeks to come,” Ben Brantley wrote in his New York Times review of Thomas Ostermeier’s production for the Berlin Schaubühne theater company.

Now New York theatergoers will be able to take in another Eidinger tour de force when he and Ostermeier bring their “Hamlet,” also from the Schaubühne, to BAM on Oct. 27. (The short run concludes Nov. 5.) By the end of the gripping, delirious show — which includes a hip-hop interlude, cross-dressing and Eidinger stuffing dirt into his mouth — you might be tempted to call an exorcist on this prince of Denmark.

Yet the actor does not set out to get a rise out of audience members. Rather, he uses a good old technique to draw them into the world of the play by creating a highly physical, no-holds-barred performance.

“This has much to do with my love for Bertolt Brecht,” the jovial 46-year-old actor said in between sips of a latte outside a Midtown cafe. “Brecht said, ‘Zeigt, dass Ihr zeigt’ — ‘Show that you are showing.’ I’m all the time showing that I’m an actor onstage in a play. It’s the opposite of the understanding of a Method actor: I never become somebody else.

“The only thing I try to achieve is to become myself,” he continued. “Maybe I’m more myself when I’m onstage as Hamlet than I am right now talking to you.”

Eidinger has toured the world with the Schaubühne, and his charisma and all-in approach have earned him far-flung fans. This may help to explain why in recent years he has become a familiar presence on international screens — chances are you’ve seen that really tall guy with the wide jaw line and narrowly set blue eyes without knowing who he was. He has played his share of extremists, including an industrialist plotting against the Weimar Republic in the Netflix series “Babylon Berlin” and an ice-cold Nazi officer in the BBC alt-historical show “SS-GB.” He has also effectively mined restraint in naturalistic dramas, most notably as a newly separated dad visiting his parents in the German film “Home for the Weekend,” and as an actor dying of cancer in the affecting Swiss film “My Little Sister.” (In that film, his character portrays “Hamlet” in a staging by a director played by … Ostermeier.)

Tellingly, our conversation took place while Eidinger was in town for the New York Film Festival, where he helped introduce Noah Baumbach’s latest feature, “White Noise,” in which he stars alongside Greta Gerwig and Adam Driver. The in-demand actor then had to leave our interview in a mad rush because he was running late for a meeting with the director Shawn Levy, for whom he has been starring in a series adaptation of the Anthony Doerr best seller “All the Light We Cannot See.”

One of Eidinger’s recent (and most memorable) screen turns was in the HBO series “Irma Vep,” in which he portrayed Gottfried, a flamboyant, crack-addicted German star who loves pushing people’s buttons. “I liked the idea that Lars carries the torch of the madness of 1970s German cinema,” the writer-director Olivier Assayas said this summer in a video chat about his show. “Somehow he’s like the Who breaking their guitars onstage. It’s stuff I grew up on and I think that’s something that’s missing in contemporary cinema.”

It’s missing on contemporary stages, too, giving Eidinger’s self-aware hyper-theatrical performances a unique power. But if they resonate with theatergoers past the initial shock to the system, it’s because he never loses sight of his characters.

EIDINGER GREW UP in Berlin, where he still lives with his wife and daughter, and studied theater there. He became a salaried member of the Schaubühne ensemble in 1999, though he admits that it took him a while to find his bearings as a professional actor. A production of “Troilus and Cressida” with the British director James Macdonald, in 2005, proved to be a turning point. “I was really lost as Troilus, and I asked James, ‘Can you please help me understand his situation?,’” Eidinger recalled. “He said, ‘Lars, just the words. Just the words.’”

Eidinger confessed that at the time he didn’t quite get what Macdonald meant. It hit him a few years later, when he started to rehearse “Hamlet,” which premiered in 2008 and has been touring on and off ever since.

“Suddenly I thought, “OK, he was absolutely right — it’s just about the words,’” Eidinger said. “Just try it at home: Say the line ‘To be or not to be’ and try to understand what it means for you. I guarantee that there will be an emotion coming up. I don’t have to go onstage with any kind of preparation for the way I go into a mood or to a certain kind of emotion. I go onstage and try to be as open and blank as possible, and then it’s just about the words.” (Eidinger is so attached to “Hamlet” that a forthcoming documentary about him is titled “To Be or Not to Be.”)

While it takes some preparation to achieve that state of readiness, Eidinger claims that he doesn’t start from high concepts. “There’s a very nice quote from Helene Weigel: ‘If you have an idea, forget it,’” Eidinger said, quoting Brecht’s wife and the director of the renowned Berliner Ensemble. “I believe in the genius of creation out of the moment. You invent something out of an impulse because you are open-minded, but you are not aware how meaningful it is. For example, in ‘Hamlet’ I wear the crown upside down,” he continued. “We tried several crowns and then we had one that was a bit too big for my head and always fell off. So I put it on the other way around, and then it worked.”

It probably helps that he and Ostermeier seem to have a complicated relationship that involves trust but also a degree of one-upmanship. Speaking about their rehearsals in a video conversation, the director said: “We were constantly competing on who has the more crazy idea, who is more funny, who is more inventive, who is more creative. Because we know each other so well, it’s often, ‘OK, but I know even better, it can be even more crazy.’”

And this does not stop once a show reaches the stage. Jenny König, who plays Gertrude and Ophelia in “Hamlet” and Lady Anne in “Richard III,” knows all too well that acting with Eidinger requires being constantly on alert. “I think he’s really good at creating an illusion that it’s happening the first time right now — he can’t just play the scenes like he did it a hundred times before,” she said in a video chat. “It’s always this special moment where something else could happen. Sometimes it doesn’t work, that’s the risk, but the aim is to be in the moment and to experience real reactions.”

Onstage, Eidinger is in a heightened state of consciousness that allows him to experience a hyper-awareness of his environment. That, in turn, helps him modulate and adjust his performance on the spot. “Some actors describe acting like being a tunnel, but it’s the complete opposite for me: I’m aware of everything,” he said. “I’m standing onstage, maybe I’m emotional and crying real tears, but at the same time I see the person in the first row taking candy out of his pocket and eating it. I can think about bringing my daughter to school. It doesn’t distract me: It makes it more complex.”

This openness to his surroundings is also expressed into an interest in exploring other mediums. Eidinger, who mentions music as a primary inspiration, released a trip-hoppy album, “I’ll Break Ya Legg,” in 1998; quotes the rapper Tyler, the Creator as freely as Brecht; and has been deejaying for decades, including regular gigs at the Schaubühne. (“I’d say his taste of music is much too commercial,” Ostermeier sniffed. Someone needs to write a play à clef about these two.) He also loves taking photographs and has directed a few shows — this fall he is reprising the adaptation of “Peer Gynt” that he hatched with the artist John Bock and starred in.

“For me, there’s not a big difference in how I express myself, so I’m completely satisfied just doing photography, I’m completely satisfied just directing or doing music,” Eidinger said. “Acting is something I stick to because maybe I’m most talented. In all the other art forms, I feel limitations; when I act, I feel no limits. And that’s very attractive, of course.”
