Chris Diamantopoulos
Chris Diamantopoulos is an actor, born 1975.
Christopher Diamantopoulos was working, professionally, at nine. Born in Toronto in 1975 and raised splitting his time between Greece and Canada, he did television commercials and theatre as a child, left home at eighteen for a run of US national tours, and worked his way onto Broadway from there. That stage grounding shows up in the sheer projection of his screen work.
His specialty is the loud, self-satisfied man who stays entertaining instead of merely exhausting. Russ Hanneman on Silicon Valley is the definitive version, a venture billionaire who cannot get through a sentence without valuing himself in it, and the reason the character kept being brought back is that Diamantopoulos plays the neediness under the noise. He can also drop the volume entirely: Clark Ingram on Hannibal is genuinely unpleasant, Sotto Voce in Red Notice is a villain played with a light touch, and Marky Bark on Arrested Development is committed idiocy of a very specific kind. As Moe in The Three Stooges (2012) he attempted a full-body impersonation of a nine-decade-old comic performance, which is a harder job than the film gets credit for. He also had a supporting run on the ninth season of The Office.
The voice career is the half that pays. He has voiced Mickey Mouse across The Wonderful World of Mickey Mouse and the short Once Upon a Studio, picking up two Emmy nominations for it, and the rest is a long list of animation: Donald on Invincible, ROBOTUS on Inside Job, Evios on Blood of Zeus, Steve Trevor in Justice Society: World War II, plus the Batman Unlimited features and a stack of Diary of a Wimpy Kid specials. Sixty-odd credits and no obvious ceiling on the range.

Where to start with Chris Diamantopoulos
There is no serious competition for the entry slot here: Silicon Valley. Russ Hanneman arrives in the first season as a one-note joke about a man who got rich early, and Diamantopoulos keeps finding new floors under him without ever making the character sad enough to stop being funny.
For proof he can do the opposite, go to his episode of Hannibal, where he plays quiet, ordinary menace in a show that usually prefers the operatic kind. Arrested Development and Red Notice are the light-comic bookends, one deranged and one glossy.
The voice work rewards a separate pass. INVINCIBLE and Inside Job show the range in adult animation, The Wonderful World of Mickey Mouse is the technically hardest thing on the list, because inheriting that voice leaves nowhere to hide, and Once Upon a Studio is the six-minute victory lap. The Three Stooges is for completists and for anybody who wants to see an impersonation done properly in a film that is otherwise not for adults.
Mickey Mouse
He has been the official voice since 2013, across the shorts, the seasonal specials and an Oscar-winning short film, and has two Emmy nominations for it. The 2013 shorts are the ones that rebuilt the character.
The live-action comedy
Russ Hanneman in Silicon Valley is the one people quote, a billionaire with a tequila brand and an open shirt. The Three Stooges is a piece of physical mimicry better than the film containing it.
The adult animation
A steady run of voice work in the more ambitious animated series of the last few years. Scavengers Reign and Pantheon are the two worth seeking out and almost nobody watched either.
The dramatic turns
Where the comic energy gets pointed somewhere colder. Hannibal casts him as a social worker with a very unpleasant secret, and The Kennedys has him as Frank Sinatra.
