CORPO CELESTE. In this quiet but sharp coming-of-age dramedy from Alice Rohrwacher, 13-year-old Marta (an expressive Yle Vianello) is enrolled in a confirmation class at the local parish. But the real-life lessons she learns about the fallibility of the church and the grim banality of pre-celestial life are well outside the catechism. (In Italian, with subtitles. 7 p.m. Thu., Nov. 17, and 7 p.m. Fri., Nov. 18, Regent Square)
ECO-PIRATE: THE STORY OF PAUL WATSON. Trish Dolman's documentary has three intertwined narratives. One documents the early years of Greenpeace, founded in 1971 in Vancouver, as a hybrid of the peace and ecology movements. The group quickly gained international fame for high-profile protests against whaling and the killing of baby seals. (Warning: graphic footage.) The second thread profiles Paul Watson, who broke away from Greenpeace to found Sea Shepherds, an anti-whaling group that adopted a more aggressive style. (Watson infamously sunk a whaler.) Lastly, the film crew rides along on a recent voyage as the Sea Shepherds try to catch Japanese whalers operating near Antarctica. Throughout, Eco-Pirate wrestles with the dichotomy of Watson, whose unrepentant intensity for saving whales often undoes his personal, and occasionally professional, life. (9:30 p.m. Thu., Nov. 17, Melwood)
