As the woman gives birth, her right hand jumps between being wrapped around Curt's neck, tearing his shirt to being calmly placed on his back.
At the end of the movie, during the initial end credits where a few actors are actually shown and subtitled with both their real name and character name, the actress "Julie Claire as Judy" is incorrectly displayed as "Judy Claire as Judy". Later, the B&W scrolling end credits do have her listed correctly.
