Screen legend Janet Leigh, whose shocking first-act murder in the classic Alfred Hitchcock thriller Psycho stunned audiences and stigmatized motel-room showers forever, died Sunday at her home in Beverly Hills. She was 77. Leigh's husband, Robert Brandt, and her daughters, actresses Kelly Curtis and Jamie Lee Curtis, were at her side. Leigh, whose other credits include the original The Manchurian Candidate and Orson Welles' 1958 film noir Touch of Evil, had suffered from vasculitis, an inflammation of the blood vessels.
