The greatest film to date by poet, critic, curator, and director Jonas Mekas, this highly personal 1971 feature chronicles his first trip back to Semeniskiai, Lithuania, the village where he was raised, after an absence of 25 years. It’s a moving act of memory and self-scrutiny, reflecting in some respects the diary films he’s made since the 60s but clearly standing apart from them. Narrated by Mekas, the film opens with footage of his first years in America and closes with contemporary visits to a Hamburg suburb (site of a labor camp where he and his brother Adolfas spent a year during World War II) and Vienna (where he enjoys the company of several friends, including filmmaker-curator Peter Kubelka and critic Annette Michelson). But its centerpiece, entitled “One Hundred Glimpses of Lithuania, August 1971,” is the segment that shows his highly charged sense of film poetry at its most distilled and emotional. Essential viewing. 82 min.
