Most reviews by IMDB members of this film are ecstatic and with very good reason. This must surely be director Willy Forst's greatest achievement. There is a magic alchemy at work here by which everthing gels. Cinematography by Franz Planer and music by Willy Schmidt-Gentner,played by the Vienna Philharmonic, only add to the films irresistible appeal.What can one say about the cast?! Olga Tschekowa is the woman scorned; Peter Peterson is the doctor who has to make a choice between personal feelings and professional ethics and Hilde von Stolz is his deliciously flirtatious wife whose reading of the line' I am not interested in art, only artists' is unforgettable. Anton Walbrook as the painter brings as always his particular air of mystery. What woman could resist his magnificent chat up line 'You are too beautiful not to be painted'! This film however really belongs to Paula Wessely. It took me a while to forgive her for appearing in the egregious 'Heimkehr' but artistes in those extraordinary times very often made decisions which they had cause to regret and which came back to haunt them. A talent such as hers comes very seldom however and in this she is simply magnificent. As a post-script there is an uncredited appearance by Lisl Handl who was married to the co-writer Walther Reisch. He was a fine director in his own right for whom Lisl starred in 'Silhouetten' in 1936. They went together to Hollywood where she was condemned to appearing in anti-Nazi propoganda films in which she acted under the professional name of Poldi Dur which just happened to be the name of Paula Wessely's character in 'Masquerade'! Willy Forst's masterpiece is also sub-titled, so how could one possibly not see it?! Full marks all round.
