Earth Day Docs at Bay Street Theater

The Hamptons Take 2 Documentary Film Festival will celebrate Earth Day with a double feature of two nature films on Sunday afternoon at Bay Street Theater in Sag Harbor.

“Mission Blue,” the Emmy Award-winning documentary directed by Fisher Stevens and Robert Nixon, follows the marine biologist and activist Sylvia Earle over a three-year period while she traveled the world’s oceans to draw attention to and challenge their degradation by overfishing, dumping, and drilling.

The free screening of “Mission Blue” will take place at and 2 and be followed by a question-and-answer session with Carl Safina, the founding president of Stony Brook University’s Blue Ocean Institute.

“Bird of Prey,” a documentary from the Cornell Lab of Ornithology, focuses on the Philippine eagle, the world’s largest and rarest, and the expedition to the Philippines by a group of environmentalists and the wildlife cinematographer Neil Rettig to focus on the habitat loss and hunting and trapping that threaten it with extinction.

Tickets to “Bird of Prey,” which will be shown at 4, are $20 and available at the Bay Street box office and ht2ff.com.
