Auberjonois will play the role of Jeff, currently played by Tony Award nominee Jeremy Shamos (Clybourne Park), who will offer his final performance July 7. Auberjonois' stage credits include Death of a Salesman and Equivocation.
The Assembled Parties, starring Tony Award winner Judith Light and Tony Award nominee Jessica Hecht, will continue performances through July 28 in the third and final extension for the production.
MTC artistic director Lynne Meadow staged the play that officially opened on Broadway April 17 after previews that began March 21 at the Samuel J. Friedman Theatre.
The production received three Tony Award nominations: Best Play (Richard Greenberg), Best Featured Actress (Judith Light) and Best Scenic Design of a Play (Santo Loquasto). Light, who received the Tony Award, is the first actor to win consecutive Tony Awards in almost 20 years.
According to MTC, "The Assembled Parties welcomes us to the world of the Bascovs, an Upper West Side Jewish family in 1980. In a sprawling Central Park West apartment, former movie star Julie Bascov (Tony Award nominee Jessica Hecht) and her sister-in-law Faye (Tony and Emmy Award winner Judith Light) bring their families together for their traditional holiday dinner. But tonight, things are not usual. A house guest (Tony nominee Jeremy Shamos) has joined the festivities for the first time and he unwittingly — or perhaps by design — insinuates himself into the family drama. Twenty years later, as 2001 approaches, the Bascovs' seemingly picture-perfect life may be about to crumble. A stunning new play infused with humor, [it's] an incisive portrait of a family grasping for stability at the dawn of a new millennium."
