The surreal comedy series - created by stars Chris Bran and Justin Chubb - will return to Sky Atlantic in summer 2013.
The series two premiere will see Maven (Chubb) and Sporall (Bran) joined by a host of new characters, including tweedy professor Dr. Bevelspepp (Fry) and the sinister Jennitta Bishard (Greg Davies).
Later episodes will introduce flamboyant psychic Madame Astralina (Katy Brand) and school-mistress Miss Penny (Dame Eileen Atkins).
Ben Miller will play the dual role of the Chief Accountant of Jinsy and his buck-toothed accountant daughter Berpetta.
Additional cast additions include Sir Derek Jacobi as Jinsy's eldest resident Robune Barnatty, Stephen Mangan as Mr Lovely - owner of Mr Lovely's Lovely Jumper Shop, Rob Brydon as singing sensation Rex Camalbeeter, Phil Davis as Roley Jenkins and Olivia Colman as his wife Joan.
The first series of This Is Jinsy aired in late 2011 and was nominated for a British Comedy Award in December.
