The Questors Theatre is an independent theatre in Ealing, West London. Established in 1929, The Questors produce between fifteen and twenty main season shows a year as well as hosting productions from visiting companies. In 1964 The Questors completed the construction of a new theatre building, which was opened by Queen Elizabeth the Queen Mother. This new theatre's adaptable configuration was one of the first in a new wave of thrust stage theatres in Britain. In October 2014, to celebrate the fiftieth anniversary of the opening, it was renamed the Judi Dench Playhouse after the company's patron. The site also contains a studio theatre (the Constantin Stanislavsky Room, built as a rehearsal room in 1960 and converted into a studio theatre in 1968), three rehearsal rooms (the Bernard Shaw Room built in 1958; the Michael Redgrave Room, opened in 1968, converted from part of the original Mattock Lodge; and the Alfred Emmet Room built in 1998), a scenery workshop, and a members' bar (The Grapevine, opened in 1959, converted from part of Mattock Lodge. The company also runs an academy offering everything from intensive training programmes to fun and friendly weekly classes for adults and a thriving youth theatre.
