Brit Marling, Alexander Skarsgard and Ellen Page look properly menacing on the first poster for eco-terrorist Sundance thriller “The East.” Marling’s second collaboration with “Sound of My Voice” director Zal Batmanglij earned mostly praise from Sundance back in January, and is preparing to the slightly more hipster SXSW crowd tomorrow night.

Marling plays a young corporate contractor infiltrating an eco-terrorist organization intent on carrying out destructive acts on companies they believe are committing crimes against nature. Page, Skarsgard, Shiloh Fernandez and more play members of the group, and the film drew muted responses from its first audience at Sundance, most of whom agreed it was great, though perhaps not as great as Batmanglij and Marling’s first film.

“The East” will be released on May 31st. The first poster is below and the first trailer – ICYMI – is here.
