The distinctively camp, adenoidal tones of actor Robert Longden have been heard in some minor classics of British TV. His whimsical annunciation (somewhere between Georgina Hale and Julian Clary) and strangely boyish manner means he tends to appear in eccentric pieces, notably Alan Plater's Beiderbecke trilogy, in which he played Mr Pitt, the quietly subversive planning officer.
Other TV roles date from the early '70s to the '00s, and include: 'The Fenn Street Gang', Sapper Copping in 'Danger UXB' (pictured above), 'Peter Cook & Co', 'Wood & Walters', 'Boon', 'The Gentle Touch', a string of TV movie whodunits and the unavoidable 'Casualty' and 'Doctors'. His showreel would suggest that he's keeping fairly busy, but I don't think he quite hooked as many primetime shows as he deserved.
