I love almost everything about this movie.  It’s such a ton of fun.  One of the subway hostages in the movie was played by a woman whose daughter was my babysiter when I was mad young.  Also, years later, when I worked in the movie business, I got to know the wife of the sound guy.  She is a wonderful New Yorker, with stories for days and the accent and attitude to match.  She grew up in Little Italy, and her husband recorded wild sound for most of the movie’s audio.  In the final scene, when the subway screeches into a downtown station, the sound effects came from sliding the shower rings in their bathroom.
