Guillermo Del Toro was born in Guadalajara, Jalisco, Mexico, the son of Guadalupe Gómez and Federico del Toro Torres, an automotive entrepreneur. He was raised in a strict Catholic household. Del Toro studied at the Centro de Investigación y Estudios Cinematográficos, at the University of Guadalajara. When del Toro was about eight years old, he began experimenting with his father's Super 8 camera, making short films with Planet of the Apes toys and other objects. One short focused on a "serial killer potato" with ambitions of world domination; it murdered del Toro's mother and brothers before stepping outside and being crushed by a car. Del Toro made about 10 short films before his first feature, including one titled Matilde, but only the last two, Doña Lupe and Geometria, have been made available. He wrote four episodes and directed five episodes of the cult series La Hora Marcada, along with other Mexican filmmakers such as Emmanuel Lubezki and Alfonso Cuarón. Del Toro studied special effects and make-up with special-effects artist Dick Smith. He spent 10 years as a special-effects make-up designer and formed his own company, Necropia. He also co-founded the Guadalajara International Film Festival. Later in his directing career, he formed his own production company, the Tequila Gang. In 1997, at the age of 33, Guillermo was given a $30 million budget from Miramax Films to shoot another film, Mimic. He was ultimately unhappy with the way Miramax had treated him during production, which led to his friend James Cameron almost coming to blows with Miramax co-founder and owner Harvey Weinstein during the 70th Academy Awards.
