You've no doubt noticed that almost every phone number in the movies starts with "555." But you may not have realized just how many movies actually mention these phone numbers.
The "555 Supercut" gathers together clips from just a handful of movies that feature the magical digits and, oh my, there are so many! Someone with a lot of free time and even more patience should put together a "Movie Phonebook" with every fictional character and business listed with their respective numbers -- there's probably a lot of overlap.
(Actually, someone probably already has done that -- at least sort of, anyway.)
Put a call into "Ghostbusters," "Dumb and Dumber," "Scream," "Back to the Future," "The Fog," "Carlito's Way," "Do the Right Thing," "Say Anything," at least two of the "Die Hard" adventures and, of course, "Last Action Hero," among many others, courtesy of YouTube.
