As his 50th anniversary as a playwright approached, David Williamson decided the time had come to retire – an announcement he made last year. And so it is that his half century writing for the stage coincides with his final new plays. He’s going out with quite a bang with two new comedies currently running in Sydney, and a revival of Emerald City , co-produced by Queensland Theatre and Melbourne Theatre Company, playing in Brisbane.

The angry, powerful Family Values , which opened at Griffin Theatre Company in January, is playing to packed houses. Now comes his very last new play: Crunch Time,which is having its premiere season at the Ensemble Theatre.
