Claude Laydu was Belgian-born French actor.
Laydu was born in Brussels, and had been a theater actor when he was cast as the title priest in Robert Bresson's Diary of a Country Priest in 1950. For roughly the next decade, Laydu worked in film steadily until 1963's Mafia alla sbarra. His only two film projects after that were Le Destin de Priscilla Davies in 1979 and Nounours in 1995, which he cowrote with Christine Laydu. Laydu died 29 July 2011 in Paris of a heart condition.
