The 4th Floor (1999)

A young woman (Juliette Lewis) decides she wants to live by herself for awhile rather than moving in with her boyfriend (William Hurt). When she moves in to her new apartment, everything seems fine at first but things quickly turn bizarre. Written and directed by Josh Klausner (WANDERLAND). A serviceable second tier thriller that doesn't make much sense. Just why is everybody in the building weird, particularly the nutty landlady (Shelley Duvall). When Juliette Lewis is terrorized by the mysterious tenant who lives in the apartment beneath her, why doesn't she just move out? None of this is answered to the viewers' satisfaction. As to who is the perpetrator behind all this, in movies of this sort, I consider who is the most unlikely person to be the villain and I'm almost always right and in this case, it is the most unlikely person and the most likely person. With Austin Pendleton, Artie Lange, Tobin Bell and Robert Costanzo.
