DAY 1 of my Halloween Horror Movie Challenge, and I begin with my absolutely favorite movie:
Rosmary’s Baby 1968, copyright Paramount Pictures
This movie’s been a favorite of a while, for how brilliantly it captures the constant pain, worry, and terror of being pregnant and twists it in an interesting new way. I first watched it when I was pregnant with my first child, so it was extra poignant at the time. Pregnancy is, without a doubt, one of the scariest things women have to go through, and it really does feel like your own body is betraying you while being host to a strange entity, despite all your love and hopes.
Now throw into that psychological mix, two of the greatest villains: The Castavets. I love that the mundane meets the sinister in the fantastic characters of a pokey old busybody and her lovable bear of a husband.
The Face of Evil
It makes Rosemary’s Baby, one of my favorite horror movies (Polanski aside) of all time, and it’s the movie I’ll ALWAYS start any horror marathon with.

One of the few films that can really get you ‘into the head’ of a character. We have all had that feeling that something was not right while everyone else says it is. Add the pregnancy to it and you just feel soooo bad for her… and you want to punch Charles Grodin in his face
