Bossk, a brief of amicus curiae is a document in support of a particular position on a case. In Canada, we call such parties intervenors, because they are intervening on behalf of one of the primary parties to the case.
As a side note, ClearPlay has a list of films that they will not create filters for, because they feel that the filtering would render these films incomprehensible. On this list are: Schindler's List, The Passion of the Christ, Saving Private Ryan, and several others. I would not be surprised to see either of Bill Hunt's picks added to the list.
