The first vampire to die in "The Lost Boys" at the hands of the Frog Brothers (Corey Feldman and some other kid) is Alex Winter, the same actor who played Bill S. Preston alongside Keanu Reeves as Ted Theodore Logan in "Bill and Ted's Excellent Adventure"
Later in "The Lost Boys," the other blonde haired vampire (not Kiefer Sutherland, the no-name one) saw the Frog Brothers and shouted "YOU KILLED MARCO!"
In 1998, when I was in my early 20`s, I saw Corey Feldman in a nightclub, and for some reason he had makeup on. A lot of it. Years later I found out he was using heroin during that time period. Girls were practically lining up to talk to him because he used to be famous. So, I walked past him and shouted "YOU KILLED MARCO!"
