The Royal FamilyThe Royal Family will hold court at the Samuel J. Friedman Theatre tonight when it has its official Broadway opening. The 1927 comedy by playwriting greats George S. Kaufman and Edna Ferber is about a family of flamboyant theater performers called the Cavendishes (based on the legendary real-life Barrymore clan). This Manhattan Theatre Club production of the play stars a cast of theater pros, including Rosemary Harris, Jan Maxwell, Larry Pine, Reg Rogers, Tony Roberts (Broadway's Xanadu), John Glover (recently on Broadway in Roundabout's Waiting For Godot revival), and Ana Gasteyer (Wicked, TV's Saturday Night Live). Directed by Tony Award winner Doug Hughes (Doubt), the production is scheduled to run at the Friedman Theatre through November 29th.
