Stephen Merchant and Steffan Rhodri in rehearsals for The Mentalists

Award-winning funnyman Stephen Merchant and Gavin and Stacey star Steffan Rhodri are soon to appear on the West End in a new production of Richard Bean's comic two hander The Mentalists.

The production, which is directed by Abbey Wright, runs for a strictly limited season at Wyndham's Theatre from 3 July to 26 September.

The play, first seen at the National Theatre in 2002, centres on two men holed up in a faceless Finsbury Park hotel room who are forced to confront the darker side of their unique relationship.
