Amy Morton, the Tony-nominated powerhouse who gave what I think was the greatest performance of any I saw last season, returns to the Broadway company of August: Osage County on May 26. Phylicia Rashad will be donning the teal pajamas of Violet Weston on that same day. Morton left the NY production in October 12, taking a well-deserved rest before shipping off to London for the National Theatre production that opened in November.
