This is not Bergman's worst performance, in fact, she's adding another nuance to her wideranging, diverse portfolio of phantasy charcters. The working language is opposing her though, in Bergman's self evalidation decent enough for a party conversation, here, her timing reveals to be quite off in the dialogues. Some amount of mystification, at least to the accidential viewer, might involve the timing of her Germany outing, this movie however doesn't present any regime friendly note recognizable to me, and while it's not a masterpiece of subtle dissent either, the overall 50/50 result of female career vs romantic interests, the involvement of leading man Hans Söhnker, co-star Ursula Herking, not least the idea of decorationg the household flagpost with (white) underwear, do have to present the Persilschein for this movie.
