Artistic director Scott Elliott stages the American premiere of the work. Previews began Jan. 15 at Theatre Row's Acorn Theatre, and the show officially opened Feb. 7 for a run originally slated through March 8. Now, the company adds two more weeks of performances. Set in suburban London (2004-2005), Two Thousand Years centers on "an assimilated Jewish family [whose] quiet life gets turned upside down when their son becomes seriously devout," according to press notes. The play was previously seen in 2005 at London's National Theatre.

Lyonne is featured as daughter Tammy opposite Laura Esterman (Marvin's Room, Terrorism) as matriarch Rachel and Masur (Democracy) as father Danny. Jordan Gelber (Avenue Q) plays the newly-religious son Josh who finds himself at odds with his grandfather, Merwin Goldsmith (Me and My Girl). David Cale (Floyd and Clea), Yuval Boim and Cindy Katz (Well) round out the ensemble.

Known for her film work in "Slums of Beverly Hills," "American Pie," and "But I'm a Cheerleader," Lyonne also co-starred in Charles Busch's "Die Mommie Die." Other credits include "Goyband," "Party Monster," "Kate & Leopold," "Detroit Rock City" and "Pee-Wee's Playhouse."
