The Playhouse was founded by Raymond Moore. A former Unitarian Meeting House, the quaint, white shingled, 600-seat theatre features a wrap-around balcony. The theatre opened in 1927 with a production of The Guardsman starring Basil Rathbone. Among the many noteworthy productions to be staged there over the years was a 1937 Hamlet starring Eva LeGallienne in the title role and Uta Hagen, in her professional debut, as Ophelia. Bette Davis, who spent teenage summers on Cape Cod, acted there, as did Tallulah Bankhead, Helen Hayes and Gertrude Lawrence, who met and married her husband Richard Aldrich (who ran the theatre for many years) at the Playhouse. Shirley Booth acted there so often, she kept her Oscar there.
The Cape Playhouse is located in Dennis, MA, at 820 Route 6A. For more information, call (508) 385-3911.
