To paraphrase Marie Kondo, certain actors just spark joy. They’re not necessarily the lead, or even in the top billed cast, but you notice them, no matter how small or supporting the part. Maybe it’s smoldering charisma, maybe it’s a particularly funny line delivery; their mere presence is enough to make you lean forward in anticipation. Chris Diamantopoulos is one of those performers. 

In Red Notice, Diamantopoulos makes a memorable appearance as notorious (and often shirtless) arms dealer Sotto Voce, who happens to own one of Cleopatra’s priceless golden eggs, a prize every art thief is fighting to acquire. Insecure and comically pompous, Sotto Voce is precisely the kind of charmingly unlikeable character that has slowly become Diamantopoulos’ signature. And if you’re wondering where you’ve seen him before, we’ve got you covered. Take a tour through some of Diamantopoulos’ most memorable roles below — with a few surprises thrown in. 

The Sopranos 

As heir to the Barone Sanitation waste management empire, Jason Barone (Diamantopoulos) finds himself in the unenviable position of having to say “no” to Tony Soprano (James Gandolfini). Jason’s brief arc peaks in the Season 6 episode “The Fleshy Part of The Thigh,” in which his father dies and he decides to try to sell the company, oblivious to the fact that it’s a mob front used by Tony and his associates to declare legitimate income. And let’s just say, they make him an offer he can’t quite refuse. 

The Three Stooges

Cast alongside Sean Hayes (Larry) and Will Sasso (Curly) in the Farrelly brothers’ 2012 take on the classic Hollywood comedy trio, Diamantopoulos (in a Moe bowl cut) leads The Three Stooges on their slapstick mission to save their childhood orphanage. 

The Wonderful World of Mickey Mouse

Over the years, Diamantopoulos has lent his voice to shows like Family Guy, American Dad, Bojack Horseman, but his most famous character by far is none other than Mickey Mouse, whom he played in a number of television shorts and 2020’s The Wonderful World of Mickey Mouse. 

The Office

Ever wonder who John Krasinski was making those faces for as Jim Halpert in The Office? The answer is Chris Diamantopoulos. In the season 9 episode “Customer Loyalty,” we finally meet boom operator Brian Wittle (Diamantopoulos), who has been observing the Dunder Mifflin drama unfold for the past decade as part of the team filming the show’s fictional documentary concept. After Jim and Pam (Jenna Fischer) get into a fight that leaves her in tears, Brian steps in to force the cameras to stop filming so she can recover. Named after the real-life boom operator for the show, he then becomes a prominent character in the series’ final season. 

Episodes

Season 3 of Matt LeBlanc’s satirical semi-autobiographical series saw the arrival of a new boss, Castor Sotto (Diamantopoulos). Creative genius or unstable asshole? That’s the question driving most of the action as LeBlanc and the rest of the Pucks crew slog on, continuing to film a show they now hate, working for a man whose mental health appears unstable. 

Arrested Development

Diamatopoulos joined the foibles of the Bluth family in the fourth season of Mike Hurwitz’s acclaimed show as Marky Bark, Lindsay Bluth’s ostrich farmer environmentalist boyfriend.  

Good Girls Revolt

In this series based on true events, a group of young women at the fictional magazine News of the Week take a stand against their sexist male bosses. Among the latter is editor-in-chief Finn Woodhouse (Diamantopoulos), who insists that women can only be researchers, not journalists. 

Waitress

And he sings, too! In 2017, Diamantopoulos took over the role of love interest Dr. Pomatter in the Broadway musical Waitress opposite Sara Bareilles. This marked the actor’s third turn on Broadway, having begun his career onstage in 2001 as Ethan Girard in The Fully Monty, followed by a stint as Marius in Les Miserables in 2003. 

Silicon Valley

Perhaps Diamantopoulos’ best known performance to date is his turn as vile venture capitalist Russ Hanneman on Silicon Valley. In a show full of oversized and toxic personalities, he somehow manages to out-asshole everyone in the room. You have to admire the skill.
