Montalban was best-known as the mysterious white-suited Mr Roarke
Actor Ricardo Montalban, who starred in the popular US TV show Fantasy Island in the 1970s-80s, has died aged 88, a Los Angeles city official says.
The Mexican-born actor died at his home, the official said.
Fantasy Island ran for six years and centred on a magical island where guests could live out their dreams.
Montalban - who had a long career in entertainment - was also well-known for playing the villain in Star Trek, both on television and in a feature film.
Montalban's death was announced by Eric Garcetti, who represents the LA district where the actor lived.
David Brokaw, the actor's friend, described him as a "very courtly, modest, dignified individual," the Associated Press news agency reports.
Montalban had been a film star in Mexico before moving to Hollywood in 1946.
