Sebastian Sholes
I just love that name: Sebastian Sholes.
Joining such other alliterative Hitchcock characters as:
Johnny Jones
Huntley Haverstock
Herbie Hawkins
Sarah Sherman
Robert Rusk
Felix Forsythe
...plus, in a rather feminine "chick flick" of a Hitchcock movie... Sebastian Sholes, (played by Charles McGraw, the evil gladiator school boss in Spartacus) is a welcome dose of macho. Rod Taylor can't do all the work.
And I love how Sholes is talking and the waitress offers him coffee and he barks out "NO" mid-sentence and just keeps on talking.
