The Play That Goes Wrong is, ironically, a brilliant example of how it can go brilliantly right in the theatre. Mischief Theatre's play started out life in a pub theatre before being picked up by the Trafalgar Studios 2 where I saw it in May 2013. I described it as a real rib-tickler then and was delighted when I heard it was transferring to the West End proper to the Duchess Theatre.

With a West End budget behind it surely it would go from strength to strength? Well, it has. My ribs weren't so much tickled as stretched to aching point. 

They've embellished the story from the fringe production and of course the set is far more elaborate, there is even a mezzanine which adds a whole new comic element - but I'll come onto that.

As the title suggests its about a play that doesn't quite go to plan. Cornley Polytechnic is putting on a murder mystery. They don't have a great track record but this will be their 'best yet'.

The tone is set at you arrive at the theatre with back stage crew running around front of house trying to find 'Winston' the spaniel. And on stage desperate attempts are still being made to fix the set in place. It is worth arriving and taking your seat early although you may well find yourself up on stage holding the mantel piece in place.
