Auckland Theatre Company's season-opening comedy this year is a black slapstick that crowds in some favourite old gags - you know before they begin how they're going to turn out, but the comfortable nostalgia adds to the live fun.
Irish playwright Graham Linehan has done a very good job of adapting the classic Ealing Studios 1955 film into a piece that inhabits the theatre properly - placing all the action in the train-rumbled house of Mrs Wilberforce (rouge-cheeked Annie Whittle).
And what a busily decorated place Rachael Walker has designed for the old dear - the bedroom is on an angle which separates it nicely from the living room, and the bits of funny business are wonderfully framed by myriad surprising nooks and crannies.
Mrs Wilberforce's first cup of tea with the local constable (a solid performance from Paul Minifie) feels a little muffled and slow - and the step-on-the-long-scarf trick seems laboured when Professor Marcus (Carl Bland) arrives - but the criminal gang-turned-"musicians" ratchet up the energy and fun when they all burst in clutching violin cases.
