Bogart was miscast here, despite...
... the amazing sequence towards the end where he's alone in the house with Stanwyck. I thought he was great in that and the whole sequence plays out like a silent film horror.
But as a tortured artist and madman, it really needed someone with qualities more sensitive and passionate - someone like Montgomery Clift (I know he wasn't in movies quite yet - I just mean someone of his 'type').
Nevertheless I thought it was quite good in the last act. It's just a different movie than it had been up to that point.
My only other complaint really is that they should have gotten a better artist for the portraits, which were so obviously amateurish that nobody would believe they were 'masterpieces'.
