The Seattle Repertory Theatre is one of the most successful regional theatre companies in the country. This study attempts to determine the components-of its success. It concludes that the unique community acceptance and support of the Seattle Repertory Theatre is due primarily to the innovations of its Artistic Director, W. Duncan Ross, including a departure from the "permanent company" repertory theatre concept to a more flexible "nucleus company" supported by special guest artists, a shift in play selection emphasis from traditional dramatic plays to more contemporary and comedic works, and shortened .duration for each play from four to three weeks. Also examined are the growth of American Theatre, Ross's community involvement, guest directors, critical acceptance, and audience attendance.
