Heisenberg: The Uncertainty Principle - a pleasant enough evening with two great actors and great set #HeisenbergPlay ...

Last night Stuart and I went to see Heisenberg: The Uncertainty Principle at the Wyndham’s Theatre in London's glitzy West End.

Anne-Marie Duff and Kenneth Cranham are both excellent in this immaculately designed production of Simon Stephens’ frankly rather slender fable about love and physics.

Duff plays Georgie, a wild, faintly unstable 42-year-old woman from New Jersey who impulsively accosts Cranham's Alex, a solitary 75-year-old butcher, as he sits on a bench at St Pancras Station.

What follows is an improbable love story that perhaps says more about male wish-fulfilment in the idea that lonely old codgers can prove sexually magnetic to younger women than it does about quantum uncertainty. It's sweet if a little predictable.

The set design is a wow though. Bunny Christie set is beautifully mobile, white walls permit the stage space to constantly expand or contract: at one point, Georgie is hemmed in by the moving blocks and then shunts them aside, which perfectly captures her sense of entrapment and escape.

So, it was a pleasant enough evening with two great actors and great set. Maybe the plot just needed a new few more twists to keep our interest though. Rather like hearing a joke where you already know the punchline.
