David Hargreaves reached veteran standing the slow way, as a British actor whose work covers more eras of the industry than most. The first credits arrived long before the title most people know. Casting directors have gone to him for comedy more than for anything else. 61 years of work add up to around 54 titles. 'Last Christmas' remains the reference point, thanks largely to Arthur. 'Your Christmas or Mine?' is a second title with real reach.
