The use of local accents proved problematic – some actors accentuated their own speech to sound more Scottish (and provide continuity with Scottish actors Cuthbertson and Ure) while others were more comfortable with their Geordie accents. The child actors especially found losing their Geordie accents difficult and maintained them across their scenes. The actor who played Tub in Series One even made a catchphrase with his heavy accent – "What do we dee noo, Unk Ill?" ("What do we do now, Uncle?")
