Second Nature: Gender and Sexuality in the Animal World

Second Nature: Gender and Sexuality in the Animal World is a documentary comedy that examines the diversity of gender and sexuality across the animal kingdom. Following evolutionary biologist Dr. Joan Roughgarden, the film explores over 1,500 species that exhibit behaviors such as same-sex parenting, sex changes, and the formation of matriarchies. By highlighting these natural occurrences in animals like bonobos, penguins, and various fish, the film seeks to challenge the idea that queer behavior is unnatural or that females are inferior.

The film was directed, produced, and written by Drew Denny. It is a joint production from Canada and the United States by Annapurna Pictures and PageBoy Productions. The documentary features narration by Elliot Page and includes appearances by experts such as Joan Roughgarden, Patricia Brennan, Amy Parish, Joseph Graves, and Frans de Waal.

Released on June 20, 2026, with a runtime of 82 minutes, the film has a rating of 1/10 on TMDB based on one vote.
