Christopher Lee will once again serve as the voice of Death, this time for the next Sky One adaptation of a Terry Pratchett novel.

The Colour of Magic, the first in the author's 'Discword' series, sees David Jason take the role of the wizard Rincewind following his appearance in last year's successful adaptation of The Hogfather.

Jason and horror veteran Lee are joined on the cast by Tim Curry (Rocky Horror Picture Show) and Sean Astin (24, Lord of the Rings).

Filming began last week for transmission next year.
