The woman singing 'Rock-a-Bye Baby'
It struck me on my most recent viewing of this movie how truly strange this performance is. The woman is singing without any sign of emotion on her face and throughout the song she only occasionally looks inside the cradle, otherwise she's just staring blankly into space (at the camera).
She comes off as if she's going insane, and as if she loathes or at the very least is completely indifferent to her infant. The changed lyrics and the erratic and repetitive nature of the song are the result of her going crazy. There's an unhinged "end of her rope" feeling to it; motherhood is driving this woman mad. I could totally picture her smothering the infant after she finished the song.
It's strange that I didn't notice how bizarre this part was in any of my previous viewings. Obviously I'm reading too much into the song, but did anyone else find this performance to be weird and disturbing?
Edit: I just looked up the singer (Virginia O'Brien) and apparently singing stone-faced was her trademark. I wonder how weird her other performances are.
