It had its world premiere at the 2021 Cannes Film Festival in the Directors Fortnight section on July 8, 2021, and was released in the United States on June 3, 2022, by Kino Lorber to critical acclaim. Neptune Frost is the name of a black Revolutionary soldier who served in the Continental Army in 1775.
