Maura Tierney and Steven Weber will topline the Williamstown Theater Festival production of Jon Robin Baitz’s two-hander, “Three Hotels,” this summer.

Production was a last-minute addition to the Williamstown sked when the previously announced, Broadway-aimed revival of “You Can’t Take It With You” dropped out due to funding obstacles

The monologue play by Baitz, whose “Other Desert Cities” is looking likely for the Main Stem next season, centers on the dissolving marriage of an exec at an unscrupulous multinational corporation. Goodman Theater a.d. Robert Falls helms.

Other thesps signing on for stints in the 2011 slate include Richard Easton (“The Invention of Love”), cast with Holly Fain (“Gossip Girl”) and Jeremy Webb in the fest’s production of “She Stoops to Conquer,” and Donna McKechnie (“A Chorus Line”), tapped for the Rodgers-Hart catalog tuner “Ten Cents a Dance” from John Doyle (“Sweeney Todd”).

The annual legit fest in Williamstown, Mass., has long been a summer destination for Gotham legiters and auds, thanks in part to the event’s relative proximity to New York City. The event runs June 22-Aug. 28.
