Rosemary's Baby (1968) directed by Roman Polanski @ Naro Expanded Cinema

I've never seen this, but apparently it was pretty controversial at the time. Based on the novel by Ira Levin, who also wrote The Stepford Wives, This Perfect Day, and The Boys From Brazil.

RUNTIME: 137 minutes

SYNOPSIS: Waifish Rosemary Woodhouse (Mia Farrow) and her struggling actor husband Guy (John Cassavetes) move to a New York City apartment building with an ominous reputation and odd neighbors Roman and Minnie Castavet (Sidney Blackmer, Ruth Gordon). When Rosemary becomes pregnant she also becomes increasingly isolated and believes that her offspring is not of this world.

BLURBS:
"Superbly acted (especially by bone-thin Farrow and Ruth Gordon as the ultimate neighbor from hell), it's a satantango in the land of Is-this-real-or-am-I-crazy?, with a luridly literal ending that doesn't negate the previous, more interior terrors." - Ed Park, Village Voice

"It should establish Mia Farrow as an actress of stature and Roman Polanski as a name which will be remembered." - Diane Thomas, Atlanta Journal Constitution

"It is a creepy film and a crawly film, and a film filled with things that go bump in the night. It is very good." - Roger Ebert, Chicago Sun-Times
