Just saw this last night for the first time. Must say that I loved Stanwyck running, leaping, jumping, being thrown by a horse, springing up again only to leap from an eight foot fence to the ground...This was clearly no stunt double. The gal was fleet of foot, and tenacious. She loved playing tough cookies, and that's what she served up here, a tough cookie who was really heroic and unafraid. She, as opposed to Flynn, does all the swashbuckling in this movie, and it's worth seeing just for that reason alone.
And it was suspenseful...I was really quite frightened of what she would find in the lab, in the lodge, in the dumb waiter...what's that about the cold cream??? I was so edgy after she scaled the fence into the lodge compound and got lost, that I had to turn off the volume so as not to hear the scary music. So the score really REALLY adds to the suspense.
I loved Errol Flynn in his early swashbucklers, and I really liked the character turns he took in Too Much Too Soon, and The Sun Also Rises and That Forsythe Woman. But here, he's just uneven..sometimes even blank, and then other times he's okay. Clearly the writers were trying to create a Max de Winter or Edward Rochester-type character ...is he good, or bad, sincere or lying? But the execution of the idea doesn't gel enough to satisfy.
So, the writing's choppy and shallow (especially the last 2 lines of dialogue and resolution), and there's not a TON of chemistry between Flynn and Stanwyck. And yes, the other roles are either over, or under written, so you end up with shadows or stereotypes. But still, I found it fun, and there's no reason why NOT to watch this movie, unless Rebecca or Jane Eyre or Pat & Mike is playing on another channel.
