LOS ANGELES (AP) - Karl Malden, who made the words "don't leave home without it," a catch-phrase, has died. He was 97 and passed away from natural causes at his home in Los Angeles. "Don't leave home without it" was from his days as a spokesman for American Express. But, as an actor, Malden starred in the 1970s TV show "The Streets of San Francisco" with Michael Douglas. He won an Oscar for supporting actor in 1951 for his role as Blanche DuBois' naive suitor in "A Streetcar Named Desire," a role he also played on Broadway. Malden was nominated again as best supporting actor in 1954 for playing a priest in "On the Waterfront." In both movies, he costarred with Marlon Brando. One of his last acting roles was on "The West Wing."
