Cast & Crew

Jeffrey Smith (Filmmaker & Executive Producer) and Amy Hart (Filmmaker & Creative Director) met at the Heirloom Expo in Santa Rosa, CA – and the first conversation they had was about making a film together about GMOs; this conversation soon led to the creation of Secret Ingredients. Two months later they met Kathleen DiChiara – and her personal journey became the heart of the storyline. They began filming Kathleen and her family on the east coast and traveled around the country to film families and experts from coast to coast. They are deeply grateful for all of the heartfelt stories, as well as the medical and scientific expertise, shared by everyone interviewed. The film came to life with the addition of beautiful animation, motion graphics and original music by a list of talented artists. Thank you to everyone who contributed to the creation of this film.
