Horror play Ghost Stories is top of the scary League

A new supernatural horror story for the stage is to carry a warning over its shock factor.

Under-16s will be told that Ghost Stories at the Lyric, Hammersmith, is not suitable for them while those of a nervous disposition are "strongly advised to think very seriously before attending".

Jeremy Dyson, co-writer of the hit TV comedy series The League of Gentlemen, has collaborated for the first time with Andy Nyman, an actor and writer for illusionist and magician Derren Brown.

Dyson and Nyman, both 43, wanted to produce a show in the mould of cinema hit Paranormal Activity.

Nyman said The Woman in Black — which still causes audiences to scream in shock after 21 years — was the only long-running theatrical example of the genre. But he and Dyson wanted something very different.

Nyman said: "Fingers crossed, you emerge shaking and laughing and just desperate to sit and have a drink."

Ghost Stories runs from 24 February to 3 April
