  • The Atlantic Theater Company was formed in 1985. 

  • Clark Gregg is a founding member of the Atlantic Theater Company alongside David Mamet, William H. Macy, Felicity Huffman and  the rest of the NYU Class of '85.

  • Clark Gregg was once the Artistic Director for Atlantic Theater Company. He is still on the Board for the company.

  • They run as a Off-Broadway Theater  Company through the "Linda Gross Theater" in NYC. 


The Atlantic Theater Company was founded in New York City as a Off-Broadway acting company. David Mamet along with William H. Macy taught their inaugural class at New York University and started up the the Atlantic Theater Company in 1985 which consisted of the entire class. A part of that original class was Clark Gregg who graduated in 1986.


Clark has written, directed and acted in over a dozen theater acts. His theater career began earlier than his movie/tv career. His first official act in theater is credited in the year 1985 and is still going strong as his next project is a play once again under David Mamet, called "The Christopher Boy's Communion" in which Clark will be playing Alan. 

The main director and screen-writer that Clark has based his directing and writing off of is David Mamet. He gives David credit for how he channeled his writing style in his feature film "Trust Me" as he uses his style and language elements as a focus. 

When Clark Gregg graduated from NYU - Tisch School of the Arts, he graduated with a BFA in Drama. A BFA is a "Bachelor of Fine Arts" and is known as the Professional theater degree in the Arts community. 

"There were two simple life-altering concepts that I picked up while at NYU, which have sustained and defined my creative life to this day. The first was to avoid the sucking vortex of “chasing work”—an often futile and soul deadening task for recent grads—by making, producing, and writing your own. That seems daunting and it was, but finding a way to do it and doing it again even when I failed taught me everything I know. The second idea was to make the kind of work you’d like to see. This provides a powerful compass because it teaches you what you care about... in my case a first film about a sex-addicted colonial theme park worker with intimacy issues."

Clark Gregg on Advice on struggling after Acting School 

May 2018

"The Idea that the performance that your trying to have is never any further away than when the person your acting with is a life changing tenant. I can't say enough of the gift that the combination of the beautiful theory that Mamet taught us and that the working actor Macy taught us how to use. I can't say enough about what that gave me, and that gave me a craft that i will continue practicing and humbly trying to improve at until my final breath as an actor."

Atlantic Theater Company Member Spotlight: Clark Gregg


The style of acting that the Atlantic Theater Company teaches is called "Practical Aesthetics." There are 4 basic steps to breaking down a scene when using this technique. 

  • The "Literal": The essential and most basic, uninterpretive, description of what is taking place.

  • The "Want": What does one character ultimately want the other character to say or do.

  • The "Essential Action": A universal human desire that relates to the specific and essential nature of what your character wants within the scene.

  • The "As If": This relates the "essential action" to the actor's own life.

David Mamet and William H. Macy originally conceived this technique and brought it to the NYU Class and now to the Atlantic Theater Company in which Clark Gregg is one of the most famous and notable Practitioners of this technique. 

"First of all, commit the following names to memory. Caroline Seymour and Clark Gregg. The actors are twin peaks of theatrical inspiration in two thrilling staged black comedies (Mojo) Mr. Gregg is Baby, the mesmerizing man-child of Mojo. There’s a sleek sensuality about Mr. Gregg that comes to the fore in stunning moments, as when he breaks, suddenly, into a little two step across the stage. He embodies the creepy sense of peril that hands over the play all the way through to its shattering denouncement. The actor coils like a cobra in the role of Baby, the wired, unpredictable son of a murdered nightclub owner.


Listen to Mr.Gregg's baby speaking with eerie, bland sincerity of how skinny has stolen his very walk, or remembering the slaughter of a cow. (Mr. Gregg is so appealingly creepy that you forget that he's too old for the part)"

Ben Brantley, on Clark Gregg's performance in "Mojo" 

New York Times, 1997

"These men think nothing of betraying one another, let alone their lovers, and, should they get married, they do so only to avoid the bother of crawling ''through the gutter to get regular sex.'' As Jack (Clark Gregg), the most cynical of the trio, puts it: ''We're men. We do terrible things. Let's admit we like them and go on from there."

When they are sensitive or caring, chances are they are pulling a trick, the desired result of which is to lure a woman into bed. 

As directed with vitality by Mr. Macy on James Wolk's hip rollaway sets, the cast proves as promising as the author. The three leading men offer a deadly accurate sendup of masculine wiles, from the puppyish hysteria of Mr. Goldstein to the naive yet impenetrable narcissism of Mr. Lage to the witty, thinly veiled hostility of Mr. Gregg. "
