The cast of Ghosts - Mathew Baynton, Simon Farnaby, Martha Howe-Douglas, Jim Howick, Lolly Adefope and Kiell Smith-Bynoe - visit BFI Southbank to talk about their show's Christmas special and confirm that a fourth series has been commissioned. The Ghosts Christmas special will broadcast on BBC One at 20:30 on December 23rd. We join the Christmas special in the run-up to the festive season. Kitty has become convinced that Santa has made an early stop at Button House when Mike and Alison discover a man living in a tent on their grounds. The ghosts’ advice on how to deal with him leaves much to be desired, but eventually Mike and Alison learn that they have more to offer this Christmas than they realised.
