Russell Brand will host a night of solo performance about mental health.
The actor and comedian will compere Cracked, a string of one-off monologues and spoken word pieces focusing on pain and addiction.
Seven performances will be given in one night at the Old Vic in London.
Girls creator Lena Dunham and Friends star Matthew Perry are among the confirmed writers for Cracked, who will be using their own experiences for the show.
Brand said: “For this night, mental illness and addiction will adorn The Old Vic stage, celebrated, explored and attacked through Cracked.
“I am honoured to have been asked to take over the asylum, albeit for one night only.”
Other writers for the show include Scarlett Curtis, curator of Feminists Don’t Wear Pink, poet Mr Gee, physician Gabor Mate, and performer Kate Tempest.
Brand will be appearing in the show, with other performers yet to be announced.
Cracked takes place on Sunday September 29.
