I’d done voices for BBC One’s stop-motion animation The Enchanted World of Brambly Hedge in 1996 and, three years later, I was approached to play Bob the Builder. The original designs had him with a moustache, but we agreed that he looked a lot more child-friendly without one, while still being macho in his overalls and shirt.
