Oppenheimer Supporting Cast Members

Christopher Denham As Klaus Fuchs - Christopher Denham joins the Oppenheimer cast as Klaus Fuchs. Fuchs is a German theoretical physicist and an atomic spy who works closely with the Soviet Union and collects information for the Manhattan Project. As Oppenheimer is an espionage thriller just as it is a historical biopic, that element stems from Fuchs' involvement in the movie, though it doesn't become clear he's a spy until the end. Denham has starred in other historical dramas, including Argo and Charlie Wilson's War. He's best known for the series Manhattan, Billions, and Utopia.

Danny Deferrari As Enrico Fermi - Danny Deferrari's Oppenheimer character is Enrico Fermi. Fermi is an essential member of the Manhattan Project in Oppenheimer as he created the world’s first nuclear reactor. Deferrari has previously had guest starring roles in shows like Blue Bloods and producer Dick Wolf's Chicago Med, as well as acting in movies such as Private Life, State of Mind, and the TV miniseries Madoff. The actor is yet to have his major movie break, but Danny Dafarrari's place in the Oppenheimer cast should undoubtedly earn him more offers in movies.

Gustaf Skarsgård As Hans Bethe - Bethe is a nuclear physicist who made major contributions to the Manhattan Project and even won the Nobel Prize in 1967 for his work on the theory of stellar nucleosynthesis. Skarsgård is best known for his role in Vikings, and he's the son of Stellan Skarsgård. The actor comes from an extremely talented family, as he's the brother of Alexander (The Northman, True Blood) and Bill Skarsgård (It, John Wick: Chapter 4), both of whom have many impressive acting credits to their name as well.

Devon Bostick As Seth Neddermeyer - Seth Neddermeyer is a physicist who champions implosion-type nuclear weapons while working on the Manhattan Project. Devon Bostick’s biggest role to date was his stint as Jasper Jordan on The 100 from 2014-2017, and he led the Diary of a Wimpy Kid movie franchise. Nolan’s Oppenheimer movie will be Bostick's first for the great director and by far the biggest movie he's worked on to date.

David Dastmalchian as William L. Borden - Borden is used by Strauss to send a letter to the head of the FBI, J. Edgar Hoover, about Oppenheimer being a spy for the Soviets. Though he isn't an A-list actor, Dastmalchian has been in more superhero franchises than any other actor. The actor played Kurt in the Ant-Man movies, Abra Kadabra in The CW's The Flash, Polka-Dot Man in The Suicide Squad, and he was even in The Dark Knight, albeit in a small role.

Dane DeHaan as Kenneth Nichols - Nichols is an officer of the US Army who is ordered to keep a watchful eye on Oppenheimer during The Manhattan Project. DeHaan's breakthrough movie was the original superhero film Chronicle. Following that, had a huge 2010s, starring in crime dramas like The Place Beyond the Pines and Lawless. However, the actor is best known for playing Harry Osborn in The Amazing Spider-Man franchise.

Alex Wolff as Luis Walter Alvarez - Alvarez is another physicist who joins Oppenheimer on The Manhattan Project. Wolff isn't an obvious choice for a harrowing historical thriller movie, as he's a Nickelodeon alum, starring in the musical comedy series The Naked Brothers Band and released two soundtrack albums for the show. However, he has since become a brilliant actor, featuring in Jumanji: Welcome to the Jungle, and the terrifying and emotionally exhausting Hereditary.

Tony Goldwyn as Gordo Gray - Gray is a government official who was selected by Strauss to sit in on Oppenheimer's hearing. Goldwyn is best known for playing Carl Bruner in the fantasy thriller Ghost, and he also played the titular character in the 1995 biographical movie Nixon, so starring in historical movies with a political element is Goldwyn's bread and butter. The actor's voice might be more recognizable than anything, as he also voiced Tarzan in the 1999 animated Disney movie of the same name.

Emma Dumont As Jackie Oppenheimer - Jackie Oppenheimer is Robert Oppenheimer’s sister-in-law through her marriage to Robert’s younger brother Frank. Dumont has had small roles in the Paul Thomas Anderson movies Inherent Vice and Licorice Pizza, and she starred in the 2021 Wrong Turn reboot. However, the actor is best known for playing Lorna Dane/Polaris in the X-Men-inspired series The Gifted.

Scott Grimes as Counsel - Grimes is better known to some as a musician, as he released the Billboard soft rock hit "Sunset Blvd." and is part of Russell Crowe's band, Indoor Garden Party. However, like his more famous bandmate, Grimes is also an actor, having featured The Orville, The Night They Saved Christmas, and ER. The actor's most famous role is as Technical Sergeant Donald Malarkey in the HBO miniseries Band of Brothers.

Josh Zuckerman as Giovanni Rossi Lomanitz -Lomanitz is another physicist who works with the scientistsin Los Alamos. Zuckerman can be found mostly on TV, as he played Eddie Orlosky in Desperate Housewives, Mark Cullin in Kyle XY, and Max Miller in 90210. The actor's most notable role to date is his starring role in the movie Sex Drive, but Oppenheimer is his first major movie in the 15 years since.

James D'Arcy as Patrick Blackett - Blackett is Oppenheimer's tutor that Oppenheimer tries to poison by injecting cyanide into an apple. Oppenheimer isn't the first time the English actor has worked with Christopher Nolan, as D'Arcy also featured in Dunkirk, playing Colonel Winnant. The actor also has a very minor role in the Marvel Cinematic Universe, playing Howard Stark's butler, Edwin Jarvis, in both Agent Carter and Avengers: Endgame.

David Rysdahl as Donald Hornig - Horning is an American chemist and explosives expert. Rysdahl doesn't have many acting credits to his name, but he has starred in a couple of notable indie movies, including Cathy Yan's dark comedy Dead Pigs and the fantasy drama Nine Days.

Louise Lombard as Ruth Tolman - Ruth Tolman is on the National Defense Research Committee in Oppenheimer. Outside of joining the Oppenheimer cast, Lombard has starred in several long-running running drama series. Lombard played Evangeline Elliot for three years in the BBC drama The House of Eliott, and she played Sofia Curtis in CSI: Crime Scene Investigation for seven years.

Harrison Gilbertson as Philip Morrison - Morrison is a physicist who works with Oppenheimer on The Manhattan Project. Gilbertson has had tons of small roles in big movies, most notably Need for Speed. However, the actor has become a go-to name in the horror genre, as he starred in Upgrade, In the Tall Grass, and several others.

Olli Haaskivi as Edward Condon - Haaskivi is a Finnish actor who has a minor role in the Oppenheimer cast. Condon has a very brief role on the team of Manhattan Project scientists. The actor previously featured in the Edward Norton-directed Motheless Brooklyn, had a small role in The Falcon and the Winter Soldier, and has a recurring role in AppleTV+'s The Big Cigar.
