Alzheimer’s is one of the most tragic diseases for a creative person. While physically painless, the dementia and memory loss are dreadful impairments that no mind should have to bear, and that seems to be especially the case for celebrated artistic minds like that of Edwin Honig. The late poet and critic is the subject of a new documentary by Alan Berliner, the renowned maker of deeply personal experimental nonfiction films. Previous works of his include An Intimate Stranger, which focuses on his maternal grandfather, and Nobody’s Business, which is about his father. His relationship to Honig is directly spelled out in the new doc’s title, First Cousin Once Removed. In addition to that familial bond, though, Berliner considers his mother’s cousin to be his mentor and friend; Honig’s estranged adopted kids meanwhile imply that the filmmaker was treated more like a son than they each were. Making the subject matter even more subjectively relevant is the fact that Berliner’s father and paternal grandfather both suffered from dementia. So, surely this film is as much to do with the director facing his own fear that he too will one day lose cognition. It’s also his second go at the subject, as First Cousin Once Removed is an expansion of his 2010 short, Translating Edwin Honig: A Poet’s Alzheimer’s.
