In Anton Burge's new comedy, two Hollywood stars whose careers have hit rock bottom, are thrown together for the filming of the now classic film Whatever Happened To Baby Jane? The highs, the lows, the tantrums, are all exposed during this great night out at the theatre. The movie propelled them both back to stardom, but will they ever speak to each other again?
