Laddie is the strange, lonesome only child of the Lost Boys. He is both an innocent who fights the darkness of the vampire, and the proof of Star's lingering humanity. He is portrayed as a quiet, watchful child who depends on Star and adores the brotherly attention of the older Lost Boys. He is not unaware of their true nature, though. When the boys chant at Michael to drink the cursed blood, Laddie relents and runs back to the comforting presence of Star.
Laddie is advertised as a missing person, but it is possible to speculate that his parents are dead or uninterested in him for him to garner interest in the gang, as it would be unwise to initiate a child any other way. Some fans believe that David had Laddie made into a vampire as a ploy to keep Star in the gang - she certainly expresses a protective, maternal nature towards him. Out of all the boys, he is shown to be closest to Dwayne, who acknowledges him with a silent affection. He is turned back into a human at the end of The Lost Boys, and apparently becomes a vampire hunter as Alan Frog asks after him in The Thirst, but is said to have his own wife and kids now, and has moved on with his life.
Casting
Chance Michael Corbitt played Laddie in The Lost Boys. Originally Laddie was supposed to be around 14 years old in Jeffrey Boam's script for The Lost Boys and Sam Emerson was supposed to be eleven years old. In production their ages were reversed so that Sam is the teenager and Laddie is the kid. Edgar and Alan Frog were to be "chubby 8-year-old Cub Scouts". Star was actually going to be just another male member of The Lost Boys.
