Jenny closes her eyes to find out what it's like for a blind person to light a cigarette. Meanwhile, the cigarette and cigarette lighter switch hands.

In her bedroom, Joan sits on the side of her bed, takes a cigarette from a side table, holding it in her left hand with a lighter in her right. The camera goes into a closeup, and the cigarette is now in her right hand and the lighter in her left.

A blind pianist would not have sheet music stacked on top of his piano.

Sheet music has been available in Braille since the 1800s, plus a blind pianist who invites other musicians into his residence undoubtedly would have sheet music available for them.

In the opening dance sequence, Jenny Stewart is wearing regular stockings, but in the closeup of her leg, a different fish net stocking is shown.

In an old newspaper review, Tye rhapsodizes about Jenny's performance of the song "Tenderly", which he saw her perform on the night before he was shipped off to WWII (and subsequently blinded). In reality, that tune was not written until 1946, a year after war was over.
