'Seachd: The Inaccessible Pinnacle is the first feature film in Scottish Gaelic'. So says director Simon Miller, but that isn't true. That distinction is usually given to As an Eilean (1993, and also featuring music by Jim Sutherland so far as I remember).

Perhaps (though this would be surprising) he means that no English at all is used in his film. The earlier one did include some English dialogue, and the Gaelic was sub-titled.
