In this chilling exploration of fandom and fixation, retail worker Matthew (Théodore Pellerin) manipulates his way into the inner circle of Oliver (Archie Madekwe) – a magnetic artist on the brink of superstardom. What begins as a quest for access spirals into a toxic game of obsession, blurring lines between devotion and danger as proximity turns lethal.

Directed by an acclaimed indie visionary, Lurker dissects celebrity culture’s dark underbelly through an electrifying cast of rising stars and character actors. Each performance amplifies the tension between artistic ambition and parasitic fixation. Discover the players in this high-stakes psychological showdown.

Lurker main cast and supporting cast

1. Théodore Pellerin as Matthew

Québecois actor Théodore Pellerin (b. 1997) broke out in Xavier Dolan’s It’s Only the End of the World (2016), earning Cannes acclaim. His chilling range shines in Genesis (2018) as a cult recruit and HBO’s The Staircase (2022) as Michael Peterson’s troubled son. Recent work includes Solo (2023) as a drag artist and Beef (S2).

As the titular “lurker,” Pellerin weaponizes his ability to oscillate between vulnerability and menace. Matthew’s retail-worker anonymity masks calculating ambition – a role demanding unnerving subtlety as his infiltration curdles into life-threatening fixation.

2. Archie Madekwe as Oliver

British rising star Archie Madekwe (b. 1995) garnered attention in Midsommar (2019) and See (2021–2022) before leading the blockbuster Gran Turismo (2023). His stage roots (The Price) inform nuanced performances in Saltburn (2023) and Apple TV+’s Sugar.

Madekwe embodies Oliver’s artistic magnetism and escalating paranoia. As Matthew’s obsession deepens, Oliver’s ascent becomes a prison – showcasing Madekwe’s talent for conveying charisma undercut by visceral dread.

3. Sunny Suljic as Jamie

Suljic (b. 2005) broke out as the skate prodigy in Mid90s (2018) and voiced Atreus in God of War. Roles in The Killing of a Sacred Deer (2017) and Don’t Worry Darling (2022) highlight his eerie emotional precision. Jamie likely serves as Oliver’s bandmate or creative collaborator. Suljic’s casting suggests a character caught in the crossfire – his youthful authenticity contrasting the film’s predatory themes.

4. Cam Hicks as Sebastian

Emerging actor Hicks appeared in Swarm (2023) and indie shorts. His casting hints at a role within Oliver’s management team or entourage. As Sebastian, Hicks may represent industry gatekeeping – either enabling Matthew’s access or sensing his threat. His presence amplifies the film’s critique of celebrity insularity.

5. Chaize Macklin as The Fan

Macklin’s credits include The Idol (2023) as background talent. This role suggests meta-commentary on extreme fandom. “The Fan” epitomizes the public’s obsession that Matthew weaponizes. Macklin’s performance likely mirrors real-world stan culture, blurring admiration and entitlement.

6. Zack Fox as Swett

Comedian-actor Fox (b. 1991) is known for Atlanta (Bibby) and viral rap satire. His dramatic turn in Shadows (2023) revealed untapped range. Swett’s name implies industry sleaze (A&R, promoter). Fox’s subversive humor adds dark levity, potentially exposing music industry exploitation that enables Matthew.

7. Daniel Zolghadri as Noah

Zolghadri (b. 1999) stunned in Eighth Grade (2018) and Prisoners of the Ghostland (2021). Indie thrillers like Bodies Bodies Bodies (2022) showcase his anxious intensity. Noah could be Matthew’s coworker or Oliver’s skeptic friend. Zolghadri excels at characters spotting chaos early – a likely foil to Matthew’s manipulations.

8. Brian Niles as Concerned Fan

Character actor Niles appeared in The Marvelous Mrs. Maisel and Law & Order. His “Concerned Fan” role suggests moral contrast. Unlike Macklin’s “The Fan,” Niles may represent conscientious fandom – a bystander sensing Matthew’s danger but powerless to intervene.

9. Havana Rose Liu as Shai

Liu (b. 1998) broke out in No Exit (2022) and A24’s Problemista (2023). Her indie presence signals artistic credibility. Shai’s name implies mystique (possibly Oliver’s muse or ex). Liu’s ethereal quality makes her character a potential pawn or disruptor in Matthew’s game.

10. Sean Wang as Photographer

Sundance winner Wang (director of Dìdi) appears in front of the camera here. His role is symbolically potent. The Photographer literalizes voyeurism – framing Oliver’s image while unwittingly aiding Matthew’s surveillance. Wang’s casting nods to media complicity.

11. Myra Turley as Grandma Christine

Veteran Turley (Deadwood, Big Love) brings gravitas to limited screen time. Her role anchors Matthew’s backstory. Grandma Christine likely represents the “normal life” Matthew rejects. Turley’s warmth creates tragic contrast with her grandson’s descent.
