Cast of IT Chapter 1 – Full Actors List and Key Roles

IT Chapter One (2017) brought Stephen King’s sprawling horror novel to the big screen with a cast that blended established performers with then-unknown young talent. Directed by Andy Muschietti, the film follows a group of outcast kids in Derry, Maine, who face their deepest fears in the form of an ancient entity that takes the shape of a clown. The cast became a significant talking point even before the film’s release, with particular attention drawn to the portrayal of the malevolent Pennywise and the chemistry among the young ensemble that would go on to find broader fame.

The film premiered on September 8, 2017, carrying an R rating and running for two hours and fifteen minutes. Its box office performance exceeded expectations, grossing over $701 million worldwide against a $35 million budget. Behind the camera, the screenplay came from Chase Palmer, Cary Joji Fukunaga, and Gary Dauberman, while Roy Lee, Dan Lin, Seth Grahame-Smith, David Katzenberg, and Barbara Muschietti produced the project. Benjamin Wallfisch composed the score, creating the unsettling auditory landscape that accompanied the visual terror.

Who Is the Full Cast of IT Chapter 1?

The cast of IT Chapter One centers on three distinct groups: the seven children who form the core ensemble known as the Losers’ Club, the antagonist Pennywise portrayed by Bill Skarsgård, and the supporting players who populate the town of Derry. The casting process, overseen by casting director Rich Delia, prioritized chemistry between the young actors above all else. Director Andy Muschietti specifically sought relatively unknown talent for the children’s roles, believing authenticity would resonate more strongly with audiences than celebrity casting.

Who Played Pennywise in IT Chapter 1?

Bill Skarsgård assumed the role of It, manifesting primarily as the circus clown Pennywise the Dancing Clown. The character represents an ancient, shape-shifting entity that awakens every 27 years to feed on the children of Derry, Maine. Skarsgård’s portrayal diverged significantly from Tim Curry’s memorable turn in the 1990 miniseries, offering a more animalistic, unpredictable interpretation that emphasized the character’s predatory nature. The actor spent hours in makeup daily, and his performance drew heavily from horror classics and his own interpretations of childhood fears.

The casting process for Pennywise proved notably challenging. Will Poulter had originally been attached to the role but departed due to scheduling conflicts with Maze Runner: The Death Cure. Other actors who entered consideration included Mark Rylance, Ben Mendelsohn (who reportedly declined after negotiations collapsed over a pay cut), Kirk Acevedo, Hugo Weaving, Jenny Slate, and Tilda Swinton. Skarsgård’s final selection came on June 3, 2016, after what sources described as extensive final negotiations. According to interviews, Skarsgård studied various sources to inform his characterization, including a study of how clowns have historically been portrayed in folklore and entertainment.

Who Are the Losers’ Club Actors?

The seven young performers who comprise the Losers’ Club form the emotional core of the film. Each actor brought distinct qualities to their respective roles, creating an ensemble that audiences connected with despite the horror elements surrounding their characters. The casting for these positions was announced on June 2, 2016, with the young performers joining the project while still relatively unknown to mainstream audiences.

Jaeden Martell as Bill Denbrough

Jaeden Martell, credited as Jaeden Lieberher at the time, portrays Bill Denbrough, the de facto leader of the group. Bill carries the guilt of his younger brother Georgie’s disappearance, which manifests in his pronounced stutter. The character drives much of the narrative as he searches for answers about Georgie’s fate. Martell had previously appeared in St. Vincent (2014) and Midnight Special (2016), giving him more prior experience than several co-stars. His chemistry with the ensemble read clearly onscreen, with the actor handling the emotional weight of Bill’s storyline effectively.

Sophia Lillis as Beverly Marsh

Sophia Lillis took on the role of Beverly Marsh, a tomboy navigating a difficult home life under an abusive father. This marked her first major film role, though it would prove a breakthrough performance. Lillis brought vulnerability and strength to the character, earning critical recognition that launched her career. She would later star in HBO’s Sharp Objects (2018) and Netflix’s I Am Not Okay with This (2020), establishing herself as a significant young talent in the industry. Her performance in IT Chapter One particularly stood out for balancing the character’s toughness with emotional depth.

Finn Wolfhard as Richie Tozier

Finn Wolfhard portrayed Richie Tozier, whose rapid-fire jokes and comic relief provide moments of levity amid the terror. Richie wears distinctive glasses that have become iconic among fans of the film. Wolfhard was already involved in filming Netflix’s Stranger Things when cast, creating an unusual overlap between two major genre productions. His experience working in front of cameras in genre material served him well in navigating the intensity of IT Chapter One. The actor’s subsequent career has included both acting and music, with his band Captain Cookie releasing music independently.

Jack Dylan Grazer as Eddie Kaspbrak

Jack Dylan Grazer took the role of Eddie Kaspbrak, whose severe hypochondria drives much of his characterization. Eddie’s mother has instilled in him a profound fear of illness and germs, creating psychological vulnerabilities that the entity exploits throughout the film. At 11 years old during filming, Grazer was among the younger members of the core ensemble. His career has expanded considerably since, including roles in Beautiful Boy (2018) and notably providing the voice for Luigi in The Super Mario Bros. Movie (2023).

Jeremy Ray Taylor, Chosen Jacobs, and Wyatt Oleff

Jeremy Ray Taylor portrayed Ben Hanscom, the new kid in town who is overweight and possesses a poetic nature that emerges through his encounters with Beverly. Chosen Jacobs played Mike Hanlon, the sole member of the group who remains in Derry as an adult, ultimately convening the reunion in the sequel. Wyatt Oleff portrayed Stanley Uris, the cautious member of the group whose Jewish identity plays into his characterization and family background. All three were relatively new to professional acting, with their performances in IT Chapter One representing significant early career milestones.

Who Played Key Supporting Roles?

Beyond the core ensemble, the supporting cast populated Derry with characters who ranged from threatening to sympathetic to victimized. Nicholas Hamilton’s portrayal of Henry Bowers established the film series’ primary human antagonist, a bully whose descent into madness ties him to the entity’s influence. The character would return in the sequel, with Hamilton the only child actor from the first film to portray an adult version of his character through de-aging techniques.

The Bowers Gang and Minor Characters

Jake Sim played Reginald “Belch” Huggins and Logan Thompson portrayed Victor “Vic” Criss, completing Bowers’ circle of violent friends. Owen Teague appeared as Patrick Hockstetter, a character given expanded presence in the adaptation. Jackson Robert Scott portrayed Georgie Denbrough, whose fate at the film’s opening sets the entire narrative in motion. Despite appearing primarily in the opening sequence and a few brief visions, Georgie’s presence casts a shadow over Bill’s arc throughout the film.

Adult Supporting Cast

The adult cast members who portrayed the children’s parents and authority figures included Stephen Bogaert as Alvin Marsh (Beverly’s father), Geoffrey Pounsett as Zack Denbrough (Bill’s father), Pip Dwyer as Sharon Denbrough (Bill’s mother), and Molly Atkinson as Sonia Kaspbrak (Eddie’s mother). Steven Williams played Leroy Hanlon (Mike’s grandfather), and Ari Cohen portrayed Rabbi Uris (Stanley’s father). These performances established the familial dynamics that inform each child’s vulnerabilities.
