Ricardo Montalban passed away today. He was best known as Mr. Rourke from Fantasyu Island, but Trek fans will always remember him as the genetically engineered Khan Noonien Singh from the Original Series episode "Space Seed," and probably more notably, in the AWESOME 1982 feature film Star Trek II: The Wrath of Khan.
