Para mí estas cosas son como una cebolla, entre más capas descubres, más vas llorando. No hay vencedores en las guerras, sólo sangre y vencidos. - Guillermo del Toro

The carnies know they’re carnies, [t]hey don’t try to be anything else. It’s the people in the city who pretend they are judges and philanthropists and industrialists. True rot comes when you con yourself.

(Seeing character with a wig which the producer insisted he try in a delete scene): "Look, that is Peter Frankfurt's fucking doing! Explain yourself! Look at that fucker! It's fucking Michael Bolton!"

Translation: The most interesting thing in nature is that two species exist, only two species, which are expansionist: mankind and insects. All other species are territorial. The insect is a devourer, an expander, it keeps on expanding so much and it doesn’t even care. And mankind is like that, as well… The two species which are going to end up fighting over the world are going to be insects and human beings.
