Irene Dunne stars as the title character in George Stevens' beautifully wrought film version of the Kathryn Forbes novel via John Van Druten's stage adaptation. Returning, in memory, to her childhood in 1910 San Francisco, novelist Katrin Hanson (Barbara Bel Geddes) thinks of the importance of her mother Marta's (Dunne) role in the life of the family of Norwegian immigrants. As she deals with the children's problems and aspirations, such as brother Nels' (Steve Brown) schooling, Katrin's writing ambitions, young Dagmar's (June Hedin) illness, and a thousand other daily dramas, Marta manages to make all feel equally loved. She's also able to deal with eccentrics like the blustery family patriarch, Uncle Chris Halvorsen (Oscar Homolka), the family's highly literary non-paying tenant Jonanthan Hyde (Cedric Hardwicke), and spinster Aunt Trina (Ellen Corby), who is almost afraid to announce her forthcoming wedding. A final gesture of Marta's generosity at Katrin's graduation is symbolic of the spirit that is her legacy. Despite its potential for sentimentality, the film is redeemed by its nearly flawless execution as well as its insights into the most familiar aspects of domestic life. Superbly written, acted, and directed, perhaps the film's best performer is cinematographer Nick Musuraca, whose extraordinary deep-focus compositions remind one of the equal significance of every character.
