A Palestinian filmmaker and his family were detained at Los Angeles International Airport on Tuesday after arriving to attend this weekend’s Academy Awards. The filmmaker, Emad Burnat, is nominated in the Best Documentary category for “5 Broken Cameras,” which documents the growth of a resistance movement to the Israeli separation wall in the West Bank village of Bil’in. In a series of Twitter messages, the filmmaker Michael Moore said immigration officers told Burnat he would not be allowed to enter the country even after he showed them his Oscar invite. Burnat and his family were eventually released after Moore phoned Academy attorneys. Moore quoted Burnat as saying: “It’s nothing I’m not already used to. When [you] live under occupation, with no rights, this is a daily occurrence.”
