Sudden Death, the new play by Charlotte Corbeil Coleman, is so quintessentially Canadian that it starts with the singing of the national anthem. One of the plays being showcased at this year’s Next Stage Theatre Festival, the work is a striking example of the sort of theatre the festival was created to support. A brash and startling script is well-served by a crackerjack team of artists that show off the play’s potential; if some professional theatre doesn’t snatch up the play for some future season, then they aren’t paying attention.
