Filmmaker, Oliver Quintanilla, has had a near 20-year connection with a legitimate curandera in Mexico, Natalia Martínez. After many years, filled with many personal visits for healing, and his continuous insistence, she allowed him to film five mushroom healing ceremonies, four with individuals and one with a couple. With the support of National Geographic’s All Roads Film Project, family, friends, associates and even some strangers he produced and directed the documentary film Little Saints, which is the name given to the psilocybe mushrooms by the Mazatec people. Since then, Oliver has participated in many Mazatec mushroom ceremonies with Natalia, as the receiver of the mushrooms, but also as an observer and as an assistant/apprentice to the shaman Natalia.
