"Snow" kit Harrington will voice the BBC children's film "Zog," created by the creation and production team of "Gollum Bull". The plot is cute: Zog is a passionate but often troublesome dragon who is learning to fly, roar, breathe fire and fight knights at Dragon Academy for four years, with a kind little girl bandaging his wounds every year. But will this year's one help Zog complete the most complex challenge of his life: catching a princess? Harrington will be dubbing Sir Gadabout, Hugh Skinner ("Mamma Mia 2") has joined the dubbing Zog, Lanny Henry is a voiceover, and the dubbing lineup includes Patsy Ferren, Trish Yuma and so on. The film will be shown on BBC One this Christmas.
