Addicted to Love
Guilty of... Stalking, spying, attempted murder, breaking and, ahem, entering.
This movie set the gold standard for cinematic harassment. Maggie (Meg Ryan) refused to get over her chef ex Anton (Tchéky Karyo), even though he had long since moved on. So she camped out in an apartment across the street with ineffectual astronomer Sam (Matthew Broderick) and began systematically destroying Anton's life. There was the video camera on his apartment, there were the hidden mics she placed throughout when images alone weren't enough to satisfy her obsession... and then there were the occasions on which she unleashed rats in his restaurant, snuck into his apartment to stick strawberries under his pillow (he was deathly allergic), and had sex with Sam in Anton's apartment during the strawberry-planting covert op. Who needs enemies when you have former lovers like Maggie? Lanford Beard
