Cribbins has been an actor for over fifty years, having appeared in films like The Railway Children and Daleks: Invasion Earth 2150AD, television roles including Fawlty Towers: The Hotel Inspectors, and remembered by a generation as a presenter of Jackanory and the voice of the Wombles.
Of course, for Doctor Who fans he is now firmly part of the 'family' as Donna Noble's comradely grandfather Wilfred Mott, from his brief appearance in Voyage of the Damned to achieving fully fledged "companion status" - not to mention the inadvertent cause of the Tenth Doctor's demise - in The End of Time.
The actor said:
You can't go through life expecting to get prizes. You just get on with things, which is how it should be. It's a great surprise. I'm completely gobsmacked really. My dad would have been absolutely delighted.
