What the baby looks like as described in the book (spoilers)
Near the end of the movie, we see a brief, superimposed, close-up shot of supposedly the baby's face. Here is how Ira Levin's novel describes what Rosemary sees. Quoting verbatim from the book, the baby has:
- a rosy face
- orange red hair
- golden yellow "animal" eyes with neither whites nor irises, but with vertical black-slit pupils
- claws wrapped inside mittens so the baby won't scratch himself
- small chin
