Starting a new life in the city can be difficult, but here are a few tips every New Yorker should abide by in order to, oh, say, avoid spiraling into the pit of a demented, hellish existence: 1) When your landlord tells you your apartment is cursed, don’t shrug it off; 2) When your elderly Satanist neighbors bake you tasty treats, don’t eat them; and 3) When you eventually give birth to the Antichrist, pending you ignored the first two stipulations, it might be best to just cut your losses and move on. Learn all this and more from Roman Polanski’s first American film, the iconic Rosemary’s Baby, showing tonight at the HBO Bryant Park Summer Film Festival. The terrifying classic doesn’t screen until after dark, but at least when that unmistakable lullaby begins to play, you’ll be surrounded by hundreds of people just as freaked out as you are.
