10 Worst Neighbours In Horror Movies

10. The Castevets (Rosemary's Baby)

"This is no dream! This is really happening!"

Where does one even start with the Castevets? Nosey, imposing and worst of all, they're angling to get poor young Rosemary Woodhouse knocked up with the son of Satan himself. The Bramford building has a long, ugly history of witchcraft and murder which is probably why it's so affordable by Manhattan standards.

While Rosemary's husband Guy hits it off with the elderly couple, Rosemary immediately gets bad vibes from the 2 and (quite understandably) finds them meddlesome. When Guy's ailing acting career finally launches, he decides it's time to have a kid and blink and you'll miss it, Rosemary wakes up pregnant.

We gradually discover the Castevets are not only annoying but pure evil, seducing Guy into their Satanic ways in exchange for his wife bearing the Devil's child. At no point did Rosemary get any semblance of a say in all this. It's still one of the creepiest film depictions of apartment living and urban dread of all time.

Veteran character actors Sidney Blackmer and Ruth Gordon are pitch perfect as the occult-loving couple. Both capture the fake, superficial niceness of a duo secretly out to wreak havoc superbly.
