Who Is the 'Million Dollar Secret' Host? Meet Peter Serafinowicz
The British actor and comedian previously served John Wick before he began running The Stag.

Netflix's latest reality TV hit Million Dollar Secret is here to fill the Traitors-shaped hole in our hearts. In the competition show, 12 non-celeb strangers are flown out to a lakeside chateau called The Stag, where one receives one million dollars. 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 new series has everything a reality competition fan could want, from the gorgeous locale that's my new 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 currently airing, read on to learn more about Serafinowicz's life outside of Million Dollar Secret.

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."
