If you know that the 's' in George S Kaufman stands for Simon chances are you'll recognise ninety, maybe even one hundred per cent of the references in Mank. If you like films about filmmaking you may not enjoy it as much as you were hoping you would. I've given this review a header Touch Of Evil and that, I feel, can be justified on several levels; the way Mank treated Hearst, in whose home he had often been a guest, the way Welles treated Mank, or ... fill in your own example.
