By Brian T. CohanA documentary chronicling the life and work of Blackfish star Breonna Taylor, an environmental activist who has faced abuse, sexual harassment, and assault for her work in fighting for fish rights, premiered on Saturday at the Sundance Film Festival.

The film follows Taylor as she navigates the challenges of her life while raising her daughter, Zoe, in the face of extreme adversity.

The documentary also premiered on Monday in the U.K. and Australia, and in New Zealand.

In the U., Taylor won a BAFTA and a Tony Award for her performance in the Oscar-nominated film The Last Unicorn, which was a major hit at Sundance, garnering critical acclaim.

Taylor and the filmmakers were previously collaborating on the 2015 documentary Blackfish, which follows the fate of a British trawler after its crew was accused of trafficking in shark fins.

Taylor’s work has also garnered support from the Obama administration, with the president in May pledging to use her work to highlight the plight of the ocean and wildlife.
