11 things you probably didn't know about 'The Traitors'

The first version of the show is the Dutch series "De Verraders," which premiered in 2021.

It was later adapted for the UK on BCC and the US on Peacock. Other countries, like Spain, have also developed versions of the show.

The show's concept was developed by Jasper Hoogendoorn and Marc Pos and it took years to finalize.

According to The Guardian, the premise was inspired by a real-life mutiny on a 17th-century Dutch ship.

"It's a story about people who murder each other, backstab each other, betray each other. It's a horrible story," Hoogdendoor said at a TV festival in 2023. "But it was such a fascinating story and I was thinking it's also exciting. It's so exciting to read that story and that's where the whole idea came to create the show."

He also said the show was originally going to take place on a ship and be called "The Mutineers." Pos told Variety in 2023 contestants were going to jump off the ship when they got eliminated.

But the ship made the show too complicated to produce.

So far, all of the UK and US seasons have been filmed in and around real-life Scottish estate Ardross Castle.

Per the Ardross Castle website, the 100-acre property is privately owned and doesn't offer tours or individual stays, but it can be booked for groups or events.

Cumming told TODAY.com in February 2023 that playing himself on the US version of "The Traitors" was a big part of adding an element of camp to the show.

To help bring more of his real self to the character he plays, Cumming brought many pieces of his wardrobe from home, including some of his trademark tartan suits.

Season-two cast member Johnny "Bananas" Devenanzio said he and fellow "The Challenge" alum Chris "CT" Tamburello had never watched the show before joining it.

"It's actually really funny because CT and me — and this wasn't even planned — we were the only two people on the entire show that hadn't watched the first season of 'Traitors,'" Bananas told Entertainment Weekly earlier this month.

Although it may vary by country and season, "Traitors" contestants can be subject to pretty long days of filming.

Alex Gray, who competed in "The Traitors" UK, said in a December 2022 TikTok that filming was "intense" — she spent 16 hours a day shooting the show over "about four weeks."

Meryl Williams, a season-one contestant on the UK series, said she was surprised cast members didn't get to say "a proper goodbye" to people who got sent home, or "banished."

Williams called it "the worst thing" about the show in a December 2022 TikTok.

The cast of "The Traitors" is limited to a few alcoholic beverages at a time.

Williams said in a December 2022 TikTok that the cast only got to drink every couple of nights. When they drank, she said, the amount of alcohol was limited and they only got "like one or two glasses each."

UK competitor Wilf Webster told Heat World the limit is because showrunners "don't want us to mess up and get drunk and accidentally do something."

The best time to plot with other contestants may just be in cars on the way to and from missions when the cast is divided into smaller groups.

"The cars were really great times to chat with people because you're separated and nobody can hear what you're saying," US competitor Rachel Reilly told Reality Blurred in January 2023. "In the castle, you have to whisper."

According to US contestant Arie Luyendyk, the roundtable where cast members discuss who to eliminate is even more explosive than what viewers see at home.

He told US Weekly in February 2023 there's "a lot of pointing fingers, a lot of below-the-belt stuff" that didn't air.

He added there were raw, even mean, comments made during season one that he thinks the editors removed to keep the discussion focused on the game.

Part of the challenge of competing on "The Traitors" is not always knowing how many traitors you're trying to eliminate.

"We knew that there could potentially be three to five traitors in the game," US contestant Cirie Fields told E! in 2023. "That was explained to us from the very beginning."

Gray also confirmed the lack of insight in a December 2022 TikTok video.

She said there were times during her season when cast members thought there were no traitors and the show was just a social experiment.
