Literally the last word for Hollywood trivia buffs, a celebrity death certificate is also strangely compelling. Its matter-of-fact reportage makes the famous ordinary, illuminating previously well-lit profiles with the unfiltered light of the everyday. A death certificate may also reveal information that stars assiduously concealed, such as actual birthdates. In California, home to many of Hollywood's brightest stars, death certificates are a matter of public record--and consequently an untapped mine of information.
