I voted for 'other' since, although I *can* picture Walken in the cast, I don't see him as any of the listed characters. Chris is so WONDERFULLY WEIRD that he deserves another, 'original' character. *Maybe* he could have played Oberon, but I definately see him as a weird character, and as weird as most of the DS characters were, none were weird enough for Chris unique talent.
P.S. Maybe a zombie, or a member of the Gerard's or Jeb's
Army of the Dead!
