Psychoville is a British psychological horror-thriller black comedy mystery television series created and written by and starring The League of Gentlemen members Reece Shearsmith and Steve Pemberton for the BBC.

Pemberton and Shearsmith each play numerous characters, with Dawn French, Jason Tompkins, Daniel Kaluuya and Eileen Atkins in additional starring roles.

[4] The series revolves around five different characters from different parts of England: David Sowerbutts (played by Pemberton), a serial killer-obsessed man-child who still lives with his mother Maureen (Shearsmith); Mr. Jelly (Shearsmith), an embittered one-handed children's entertainer; Oscar Lomax (Pemberton), a blind millionaire who collects stuffed toy animals; Joy Aston (French), a midwife who treats a practice doll as if it is her real child; and Robert Greenspan (Tompkins), a panto dwarf in love with his Snow White who believes he has the power of telekinesis.

In the third episode they receive a videotape showing them in an asylum together (several having previously revealed that they had been institutionalised) performing "Close Every Door" from the musical Joseph and the Amazing Technicolor Dreamcoat.

Ultimately it is revealed that Joy, Robert, David and Oscar were involved in the death of Nurse Edwina Kenchington (Eileen Atkins), who is the blackmailer's mother.

Oscar, Joy and Robert prevented her from leaving the room she was trapped in, but she somehow survived and returns to Ravenhill in the final episode looking for her locket.

At the end of the series, Mr Jolly blows up part of the asylum with most of the main characters and Kenchington inside and it is revealed that Robert has the locket.

The series ends with the revelation that David Sowerbutts is storing the corpse of his mother Maureen (who has died of cancer) in a bathtub filled with ice, suggesting that she could be resurrected by the same technique.

Shearsmith and Pemberton collaborated with Rob and Neil Gibbons to produce fictional web content to accompany the show including an interactive treasure hunt.

As they sort out the mess they have caused, it is revealed that David had killed his father by giving him an overdose of sleeping pills, thinking he was helping him because he looked tired.

Phil, a researcher for the TV series Dale Winton's Overnight Ghost Hunt, goes to Ravenhill Hospital to inspect it for a forthcoming shoot.
