LOS ANGELES -- Ricardo Montalban, the Mexican-born actor who became a star in splashy MGM musicals and later as the wish-fulfilling Mr. Roarke in TV's "Fantasy Island," died Wednesday morning at his home, a city councilman said. He was 88. Montalban's death was announced at a meeting of the city council by president Eric Garcetti, who represents the district where the actor lived. Garcetti did not give a cause of death.
