Peacock just named the 23 stars headed to Alan Cumming's castle: a Tony winner, a Hobbit, an Olympic champ and a drag queen. Here's who's in.
Peacock revealed the lineup on Sept. 18. All 23 players start as Faithfuls at Ardross Castle in the Highlands, and host Alan Cumming secretly picks the Traitors.
The Tony winner and Broadway's original Glinda in Wicked is the season's biggest name. Expect some theatrics at the Round Table.
Dominic Monaghan played Merry in The Lord of the Rings and Charlie on Lost. Now he has to sniff out liars at a castle instead of fleeing Orcs.
The Happy Endings star and former Saturday Night Live cast member joins a lineup that also includes actor Johnny Sibilly.
Singer-turned-swimmer Cody Simpson (on stage in 2012) joins two-time Olympic gold snowboarder Chloe Kim and ex-NFL running back Rashad Jennings.
Bianca Del Rio won RuPaul's Drag Race Season 6 and is famous for razor-sharp insults. Pictured in 2014, she could be the castle's deadliest tongue.
Whitney Leavitt of Hulu's The Secret Lives of Mormon Wives, seen here in 2026, brings her reality-drama instincts to Peacock's game of betrayal.
Real Housewives stars Cynthia Bailey (Atlanta), Gizelle Bryant (Potomac) and Bronwyn Newport (Salt Lake City) join Southern Charm's Craig Conover.
Love Island voice Iain Stirling joins Big Brother's Taylor Hale and Jag Bains, Survivor's Michele Fitzgerald and Q Burdette, and Bachelor Joey Graziadei.
Alan Cumming hosts again after the show won all seven of its Emmy nominations. Peacock renewed it for three more seasons; Season 5 premieres in 2027.
