Comedian Harry Hill leads the cast in this festive, one hour comedy drama – adapted from Norman Hunter’s classic children’s books by writer Charlie Higson and brought to the screen by LSM director Sandy Johnson.

Using the original short stories as inspiration, the special focuses on the madcap Professor’s wild, unpredictable experiments and a sly businessman’s plot to turn the local village into the base for a munitions factory.

Also starring Vicki Pepperdine, Simon Day, Madeline Holliday, David Mitchell and Ben Miller – the special airs on BBC One at 20:30pm on Christmas Eve!
