 It was then renamed the Pinnacle Playhouse and it has been the source of its success ever since.By the time the theatre celebrated its 50th anniversary in 2001, it had established itself as Belleville's primary (and at times only) hub for live theatre with early members including Jim Alexander, Liz Marshall and Steve Forrester still spearheading consistent high quality in its productions.Today the Belleville Theatre Guild, at Pinnacle Playhouse, puts on five shows annually.
