They say every child’s a miracle, but then again, they’ve never met Theresa (the positively beatific Lili Taylor), who is something altogether more complicated. The daughter of Joseph and Catherine Santangelo, she dreams of joining a convent in Nancy Savoca’s tenderly offbeat adaptation of Francine Prose’s fifth novel, a comic chronicle of an Italian-American family that’ll endure — by the grace of God. Starring Vincent D’Onofrio, Tracey Ullman, and Michael Imperioli.
