Crowden turned down the role of Doctor Who after the departure of Jon Pertwee, eventually playing a villain opposite Tom Baker in The Horns of Nimon.
Born in Edinburgh, Crowden's career began on the stage in many Shakepearean roles and a long period at the Royal Court. He took the role of The Player King in the original production of Tom Stoppard's play Rosencrantz and Guildenstern Are Dead. His last stage appearance was in Agatha Christie's And Then There Were None in 2006 at the Gielgud Theatre.
Crowden lived in Edinburgh and is survived by Phyllida, his wife of 58 years, and four children.
