According to the Tourism New Zealand website, director Guillermo del Toro spent a few weeks scouting New Zealand by air for locations to film the prequel to The Lord of the Rings trilogy. He said he was keen to use real locations and avoid the overuse of green screen photography.
"You have a place that is creatively driven but also technically great and, if there is anything lacking, ingenuity, craftsmanship and devotion supply this." Del Toro was reported as saying New Zealand had escaped the hype of Hollywood by focusing on pure film-making.
"Wellington is infinitely superior to Hollywood for me because this is Hollywood the way God intended ... the creation of movies in the most technically pure environment as opposed to accounting, money and marketing."
