Loosely based on a stalking case involving Madonna in the 1990s. In 1996, a violent man was convicted and sentenced to ten years for stalking and threatening the life of pop legend Madonna, with the man reportedly telling her bodyguard that he intended to slit her throat if she didn't marry him. That man would later escape the mental hospital but was quickly apprehended again before any further harm was caused.

The song the police officer is singing on the street outside Bell's house is 'Top Hat, White Tie and Tails' from the 1935 Fred Astaire film 'Top Hat'
