Based on a book by National Hunt jockey Dick Francis, the horseracing thriller Dead Cert was filmed in the village of Findon, West Sussex, U.K. When jockey Bill Davidson (Ian Hogg) is killed in a horseracing incident, his best friend Alan York (Scott B. Anthony) decides to investigate. He believes that Bill's death was not an accident, and he intends to expose the real killers. Judi Dench stars as Bill's wife, Laura Davidson, while her real-life husband Michael Williams appears as jockey Sandy Mason. Directed by Tony Richardson, Dead Cert received a U.K. theatrical release in 1974. In British slang, a "dead cert" means something that is definite. ~ Andrea LeVasseur, Rovi
