"Toni" and "A Day in the Country" at 7:30 p.m. "Toni" is one of the most realistic of Jean Renoir's films depicting the life of a group of Italian immigrants working in a quarry. Shot in an authentic environment, with newsreel-like photography, without any makeup on the actors' faces, the film is experienced as a documents "as close as possible to everyday life." "A Day in the Country" is an unfinished masterpiece, based on Guy de Maupassant's short story. It captures the atmosphere and fashions of 1880 through glorious shot compositions and in inspired by the canvasses of great impressionist painters.
