Searching for home

Filmmaker Annemarie Jacir presents a spare and moving drama based on the 1967 mass Palestinian exodus to Jordan. Trapped in a refugee camp, a young boy yearns to find his father, from whom he and his mother were separated during the upheaval. When I Saw You is now out on DVD.

Bright ‘Sparks’

Imogen Heap doesn’t need a drummer. For her fourth album, Sparks, the British songwriter created beats by sampling sounds such as the slam of a dishwasher door, a baby’s heartbeat inside a womb, and an egg cracking on a bowl. She also traveled to India, Bhutan, and China to assimilate exotic musical traditions into her electronic pop. Heap’s ambitiousness paid off. Her sparks of imagination catch fire on joyful songs such as “Minds Without Fear,” “Xizi She Knows,” and “Lifeline.”

Big oil in Africa

The “POV” documentary Big Men, directed by Rachel Boynton, explores the relationship between foreign companies and African countries after oil is discovered, focusing on the progress of American company Kosmos Energy in Ghana. The film also visits Nigeria, where militants who believe average citizens do not benefit from the discovery of oil blow up oil pipelines. The film airs on PBS on Aug. 25 at 10 p.m.
