MY prize for best theatre set goes to Tom Scott for Constellations, with a collection of balloons that seem to hover over the stage in a state of suspended animation.

The balloons are of various sizes and this eye catching backdrop certainly sets the tone for a decidedly unusual piece of theatre. An engrossing, engaging and at times moving tale about the choices we make in life, right and wrong.

It's also very cleverly written, clever without any hint of irritating smugness. So clever, in fact, you'll leave the Lowry jealous of Nick Payne's typewriter, or whatever he uses to write his plays. It certainly whetted my appetite for more - this is one Payne whose a pleasure to be around.

This is a play with a heart and a brain and what you expect from the Royal Court Theatre, a company that has, over many decades, been a byword for excitement and innovation. When they're in town I feel like a kid on Christmas morning. If only they could open a Manchester branch!

Even when there's a hint of a burgeoning romance between Richard and Marianne, Payne resists the temptation to plunder the great big book of cliches. There's an easy chemistry between Joe Armstrong and Louise Brearley who play the roles and you have to keep reminding yourself your watching actors.

Both characters are never happier than when talking about their work, taking cover in it when their relationship becomes difficult. Payne also makes you care about the characters, even though we spend just 70 minutes in their company.

A play for grown ups, that's sure to leave a deep and lasting impression on those who see it. Unmissable.
