Finally got round to watching the English-language remake of "Intermezzo" with Ingrid Bergman opposite Leslie Howard -- unfortunately I don't remember very much about the Swedish original by this stage! I have a feeling I found it vaguely unsatisfactory and was hoping for better from the remake; I seem to recall I wasn't very impressed by Gösta Ekman as romantic lead (the Cinema Ritrovato review mentions his "tendency for theatricality and over-acting in sound films", which may have been what I remembered), but I didn't find Leslie Howard's performance very satisfactory either. I think part of the problem may be that Holger Brandt simply isn't a very sympathetic part to play: he behaves appallingly towards both his family and the much younger Anita, and it's hard to make this come across as a grand romantic passion that it's beyond any of them to resist. The only time the couple are really sympathetic together is at the beginning, when the attraction is still a subliminal one and they are actually talking about subjects of shared interest instead of about their love all the time...
(And at the end of the film Holger basically gets off scot-free, while Anita simply disappears out of the story despite being the more compelling character -- I feel there should at least have been a shot of a concert poster showing her becoming a star in her own right, or something, as we have no idea what becomes of her!)

But Ingrid Bergman is undoubtedly transcendently lovely, and I thought the on-screen violin playing was extremely well handled. Whoever wrote Holger's titular composition did a good job as well -- you can see why it would be a success.
