Mulholland Drive's Diane Selwyn is:
a) a meth addict
b) a hooker
d) has delusions of gradeur
e) all of the above
I tend to go with e. It explains why Coco speaks in abortion metaphors even though she's a lesbian, why she believes she gives amazing auditions and thinks directors want to cast her and why she becomes a paranoid caffein-addicted mouth breather.
