Oskar Homolka was an Austrian film and theatre actor, who went on to work in Germany, Britain, and America. Both his voice and his appearance fitted him for roles as communist spies or Soviet officials, for which he was in regular demand. By the age of 30, he had appeared in more than 400 plays; his film career covered at least 100 films and TV shows.

I Remember Mama is a 1948 American drama film directed by George Stevens from a screenplay by DeWitt Bodeen, whose work was adapted from John Van Druten's stage play. Druten, in turn, had based his play on Kathryn Forbes' novel Mama's Bank Account, which was originally published by Harcourt Brace in 1943. The story in all its variant forms recounts the everyday life and economic struggles of a Norwegian immigrant family in San Francisco in the early 20th century. The film stars Irene Dunne as the mother, as well as Barbara Bel Geddes, Oscar Homolka, Ellen Corby and Philip Dorn. Homolka portrays Uncle Chris in the film, a role he had performed earlier in the Broadway production.
