In 2012, Nguyen co-directed and produced an animated film, Hibakusha, which chronicled the early life of a Hiroshima bombing survivor, Kaz Suyeishi. The animated film stars Karin Anna Cheung, Connie Lim, Daisuke Suzuki, Jane Lui and William Knight. Nguyen and the Studio APA crew have toured with Hibakusha throughout the United States since October 2012, and the film has gone on to receive several nominations and awards, including the Special Achievement Award and Best Animated Short at the 2013 International Uranium Film Festival held in Rio De Janeiro, Brazil.
Nguyen released his first children's book on June 2020 with Sky Pony Press and Simon & Schuster titled To Baby From Daddy, which feature his own illustrations and personal composition of paternal love and advice to his daughter.
