*This event is a rental, normal Mayfair prices and membership does not apply.

*Please take note that doors open 30 minutes before showtimes. We encourage people to arrive early. We have a small box office, a small candy bar, and a single-screen cinema, meaning that when most of an audience shows up a few minutes before showtime, it causes a bottleneck. If possible, we appreciate you arriving a little bit early to pick out your seat and get your popcorn. Thanks for your help!

In Abby Martin's second feature documentary, Earth’s Greatest Enemy reveals a hidden truth behind the climate crisis: the role of the U.S. military as the world’s largest institutional polluter. Drawing on powerful testimonies from veterans, scientists, and frontline communities, it uncovers how military operations poison ecosystems, accelerate global warming, and sacrifice the future for endless expansion. From Alaska’s melting glaciers to contaminated bases across the U.S. and toxic battlefields abroad, Earth’s Greatest Enemy delivers a provocative and unflinching examination of the untouchable institution playing an outsized role in the climate crisis.
