en Cuevana 3. Backyard Theatre is a documentary about playwright Michel Tremblay and director André Brassard’s flavourful brand of Quebec theatre, which captured the earthy wit and joual (slang) of Montreal's East End working-class neighbourhood. The film features impromptu improvisation by the cast of Les belles-soeurs and Demain matin, Montréal m'attend, two genre-defining plays.
