The Assembled Parties at Hampstead Theatre - Cast

The late Richard Greenberg’s comedy-drama first played on Broadway in 2013. His other plays include Take Me Out, Three Days of Rain and The Dazzle.

The Assembled Parties is billed a sharply observed portrait about an extended New York Jewish family, where former movie star Julie Bascov insists on taking Christmas seriously – despite her family’s reminders that they are in fact Jewish.

Jennifer Westfeldt is an award-winning actor, writer and director best known for her starring role in the hit film Kissing Jessica Stein, which she also co-wrote, and writing, directing and starring in Friends With Kids, alongside Kirsten Wiig, Maya Rudolph, Jon Hamm and Chris O’Dowd.

Her stage credits include a Tony Award nomination for Wonderful Town.

Joining Blanche McIntyre in the team are designer James Cotteril, lighting designer Malcolm Rippeth, sound designer John Leonard and casting director Anna Cooper.

Jennifer Westfeldt said in a statement: “I can’t possibly express how honoured I feel to be playing ‘Julie’ in Richard Greenberg’s brilliant, beautiful play, The Assembled Parties. To have the opportunity to dig into a character with as much light and ebullience and wit and compassion and deep, visceral humanity as she has… is a precious gift. Richard Greenberg’s gorgeous play — and indeed, his entire body of work — is filled with sparkling wit, a symphony of glorious words and rhythms, and an uncanny depth of feeling that somehow never becomes maudlin. He had an utterly original, singularly brilliant voice, yet somehow he simultaneously conjured the greatest playwrights of the modern era: he had the wit of Noël Coward, the verbal dexterity of Shaw, the poetry of Tennessee Williams, and the bittersweet pathos and searing humanity of Chekhov. Working on this play feels like an absolute dream come true for me. And to be a small part of bringing this play to London for the first time feels like a double blessing.”

Director, Blanche McIntyre said: “I am thrilled to be able to direct this exquisite, sparkling, profound masterpiece by one of America’s most brilliant and insightful playwrights. At a time when the world feels increasingly unstable, it is a pleasure to work on a piece that speaks so tenderly about the bonds of family and the passing of time, and beyond exciting to have our dazzling, internationally renowned cast bringing it to life. I look forward enormously to presenting its European premiere.”

The Assembled Parties is running at Hampstead Theatre from 17 October to 22 November 2025.
