Them There is a theatrical production collective made up of a group of comedy writers and performers, notable for working on a range of projects together including the first five series of Horrible Histories, Yonderland, and Ghosts.

[3][4][5] The collective is made up of Mathew Baynton, Simon Farnaby, Martha Howe-Douglas, Jim Howick, Laurence Rickard, and Ben Willbond.

As well as carrying over the graphic style and much of the content of the Horrible Histories book series, the approach and humour of the show was inspired by past British historical comedies, including Blackadder and the Monty Python films.

The show combined live-action sketches, which often parody other UK media or celebrities, with music videos, animations and quizzes.

Howe-Douglas starred as 33-year-old Debbie Maddox, who becomes increasingly bored with her life as a suburban stay-at-home mother until an elf (Baynton) appears from a portal in her cupboard, insisting that she's the "chosen one" destined to save the eponymous fantasy world.

It centres on a group of ghosts from different historical periods haunting a country house they share with its new living occupants (played by Kiell Smith-Bynoe and Charlotte Ritchie).

[22][23] The show was remade for an American audience, starring Rose McIver and Utkarsh Ambudkar,[24] and Mathew Baynton from the UK cast has had a guest cameo on the US version.
