The casting for this movie, and the high quality of performances, really is spot-on, and stands out every viewing. From - of course - the three leads (Davis, Henreid, Rains), to Gladys Cooper as Charlotte's mother, Ilka Chase as C's sister-in-law, Bonita Granville as C's niece, Janis Wilson (who I realize many find OTT, though I've always loved her and think she does a terrific job) as Jerry's daughter Tina, Mary Wickes https://www.themoviedb.org/person/20624-mary-wickes/discuss/5d3f6c4834e1525defe99820?language=en-US as nurse Dora, Lee Patrick as a friend made on the cruise, Katharine Alexander as Miss Trask at the sanitarium, Frank Puglia as the taxi driver - and pretty much everyone else.
Of the mentioned individuals, I always find the mother-daughter characters that Ilka Chase and Bonita Granville portray, as well as the character that Mary Wickes portrays, especially a pleasure, anytime they're on screen. Each woman gives a beautifully nuanced entirely believable appealing performance, that perfectly "nails" a fully dimensional character. Regarding Granville's character, spunky niece June, in a different young actress' hands she could, and likely would, have been strictly a bullying jerk, though as portrayed by ever-superb Granville she's somehow actually thoroughly likeable and delightful, and you realize she simply has a misguided sense of humour.
