Netflix's reality TV hit Million Dollar Secret is here to fill the Traitors-shaped hole in our hearts. In the competition show, 12 non-celebrity strangers are flown out to a lakeside chateau called The Stag, where one player receives $1 million. Unfortunately, the other 11 spend every waking minute trying to suss out the millionaire so they can take the money for themselves, eliminating one person every few days. When one person is left holding the cash, the winner takes all.
The series has everything a reality competition fan could want, from the gorgeous locale that's my dream vacation to its scathing host directing the gameplay and dishing out clues for the players to obsess over. In Million Dollar Secret, the man in charge is British actor, writer, comedian, and media personality Peter Serafinowicz. Those who recognize the Brit from his film roles may know he has experience playing the scathing maître d', though he's currently busy serving campy quips rather than an array of weapons for John Wick.
With Million Dollar Secret season 2 currently airing, read on to learn more about Serafinowicz's life outside of the reality competition.
Peter Serafinowicz is a BAFTA-nominated actor and comedian who has appeared in a Marvel movie.
Peter Serafinowicz, 53, grew up in Liverpool, England, before making his entertainment debut in 1993. After several years of performing in radio shows, he transitioned to TV and worked with several U.K. comedy legends, including Simon Pegg and Veep creator Armando Iannucci. His first major film role was voicing Darth Maul in 2001's Star Wars: Episode I –The Phantom Menace. In 2007, he created his own sketch-comedy program, The Peter Serafinowicz Show, which was nominated for a BAFTA.
Among his varied roles, Serafinowicz is best known for his comedic supporting roles in films and shows, including Shaun of the Dead, Couples Retreat, Parks and Recreation, Guardians of the Galaxy, John Wick: Chapter 2, Miracle Workers, The School for Good and Evil, and The Gentlemen. From 2016 to 2019, he starred as the titular superhero in Prime Video's The Tick. Last year, he appeared in both the live-action adaptation of How to Train Your Dragon and the Netflix Christmas movie Jingle Bell Heist.
Serafinowicz is also a prolific voice actor in animated shows and video games, and outside his acting work, the comedian has been lauded for his impressions and political satire videos. In recent years, he has toured the U.K., playing one of the characters from his sketch series, Brian Butterfield.
He was previously married to English actress Sarah Alexander for over 20 years.
In 2002, Serafinowicz met Sarah Alexander, a fellow British actor best known for starring in '90s TV shows. It is not publicly known when the pair married or welcomed their two children, though they have publicly appeared together at events and in rare videos over the years.
In April 2025, The Daily Mail reported that the couple had separated after 23 years of marriage. "It’s very sad, but the split is recent," a source told the outlet.
Stage and screen actress Alexander grew up in London and is best known for starring in British TV comedies, including The Armstrong & Miller Show, Smack the Pony, Coupling, The Worst Week of My Life, and Green Wing. She also appeared on the long-running crime drama Jonathan Creek from 2013 to 2016 and played Undine Thwaite in the Epix series Pennyworth. As for movies, she held an uncredited role in the beloved rom-com Bridget Jones's Diary and played the witch Empusa in 2007's Stardust.
He was diagnosed with ADHD at age 40.
In a 2023 interview with iPaper, the Million Dollar Secret host opened up about being diagnosed with ADHD late in life. "I only found out 10 years ago, and really even more recently than that—like a year or two ago—realized just how severely it’s affected my life," he told the outlet.
"Having ADHD for me, it’s like being a genius, and also being a total idiot," he continued. "Some things I can do really super well, and there are some very, very, very basic things that I find almost impossible. I think that’s true for a lot of people with ADHD. Things that most people find tedious, but not impossible. Like, just keeping track of your bills, and your rent, and your laundry, and keeping your place tidy and remembering where to be."
Recently, Serafinowicz also appeared on an episode of Dr. Mine Conkbayir and comedian Paul Whitehouse's podcast "I’m ADHD! No You’re Not."
He doesn't think he'd enjoy being a player on 'Million Dollar Secret.'
On the day that Million Dollar Secret season 2 premiered, Serafinowicz opened up about filming the series on the podcast "RHAP: We Know Reality TV." He revealed that he mostly keeps his distance from the players so he doesn't accidentally give any clues about the millionaire, and that he feels most like himself when he speaks to them one-on-one. Most surprisingly, the host said he wouldn't enjoy being on the other side of the game.
"If we ever played [Werewolf or Mafia] as a family or with friends, I much prefer to run the game rather than to actually participate in it. I'm such a bad liar. But when I have had to play the game, I don't enjoy it."
"I feel like it's a very tense way to spend an hour," he continued. "And [the Million Dollar Secret players] are in it 24/7 for like two weeks....That's kind of crazy, mate."
