“YOYO,” starring Pierre Etaix, Claudine Auger and Philippe Dionnet. Directed by Pierre Etaix. This elaborately conceived and brilliantly mounted comedy is Pierre Etaix’s most beloved movie, as well as his personal favorite. Beginning as a clever homage to silent film, complete with intertitles, “Yoyo” blossoms into a poignant family saga (in which Etaix plays both a father and his grown son) and a celebration of the circus Etaix adored. Chock-full of nimble sight gags and ingenious sound effects, “Yoyo” is very sweet, a little bit melancholy and wholly imaginative. Not rated. In French with English subtitles. 

Showing at: Portland Museum of Art, 6:30 p.m. Friday; 2 p.m. Saturday and Sunday
