Kiefer Sutherland in The Lost Boys

Q: The second season gave us Spike [James Martsers], the sexy-sinister platinum-blond bloodsucker. Who came up with his look?
Joss Whedon: That would be me. There's a little Billy Idol, a little Kiefer Sutherland in The Lost Boys, and every guy in a black coat. I really thought the peroxide would define his face better, though James does curse my name for the burning scalp. (Source)

Tag Line: 'Sleep all day. Party all night. Never grow old. Never die. It's fun to be a vampire.'

Trivia: "This movie invented the phrase 'vamp out', which has passed into common usage on Buffy The Vampire Slayer." (Source)
EDGAR FROG: Just so you know: If you try to stop us, or vamp-out in any way, I'll stake you without thinking twice about it. (Script Source 1+ 2)
