The surreal eight-part series, set on an island were all the inhabitants are under an Orwellian gaze, starts in September.
But even though creators Chris Bran and Justin Chubb, who also star in the show, are TV newcomers, they have attracted an impressive line-up of guest stars
Also making appearances are Jane Horrocks, Nigel Planer, Simon Callow, KT Tunstall and Kevin Eldon.
Here is the full list of guest stars and their roles:
- David Tennant appears in the first episode as Mr Slightlyman, a corrupt, camp wedding planner with bad plastic surgery.
- Harry Hill is the sinister Joon Boolay, who delivers punishments to residents across the island from the safety of her TV studio.
- Jennifer Saunders provides the Voice of Miss Reason, who delivers island announcements in every episode.
- Catherine Tate is Roopina Crale, chief editor of Glove Hygiene Monthly, who comes to Jinsy on an assignment
- Jane Horrocks is Mrs Stenton, the headteacher of The White Apron Play Group, with a peculiar attachment to a crow glove puppet.
- Simon Callow is Threcker, an officious, intense ex-teacher
- Kevin Eldon is Edery Molt, an eco-warrior who halts construction of a bridge
- Peter Serafinowicz is a conniving salesman Eric Bunt, who sports a slicked-down side parting and a cheap suit.
- Brian Murphy will play Melty Harris. He’s a posh, disorganised and slightly inebriated man who wears an ill-fitting suit and cravat.
This Is Jinsy will also feature Colin Hoult as Seebry Mungerton, Marek Larwood as Caravel Didd-Onion, Nigel Planer as Man With No Nameworm, Don Warrington as Chief Thinker, KT Tunstall as Briiian Raggatan, and Marcia Warren as Mrs Oon, the lead singer of folk-thrash-band Mool Perpya.
Producers Chris Carey and James Dean said in a statement: ‘We have been overwhelmed by the calibre of support that This Is Jinsy has attracted. It's testament to the brilliant writing and extraordinary vision of Chris and Justin.’
The show was originally piloted on BBC Three, but moved to Sky when commissioner Lucy Lumsden became head of comedy for the digital giant.
It is being directed by Matt Lipsey, whose credits include Psychoville and Little Britain.
