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. "The Ricardo Montalban Theatre in my Council District — where the next generations of performers participate in plays, musicals, and concerts — stands as a fitting tribute to this consummate performer," Garcetti said later in a written statement.
