At the end of movies there's usually a very long list of credits presented to viewers noting all of the crew and cast involved with creating the movie itself. How are these long lists compiled accurately, as to make sure everyone involved is listed correctly for legal/professional purposes. The list can list over 100 different names at times, and many different titles. Who's job is it to compile that list? How does one know the name of every best boy, production assistant, small-role actor, accountant, makeup artist, and whoever else involved? How are lists such as those verified for accuracy? How long can it take to compile them? If you've done your own, how did you do them? If you know of others who have done them, how did they do theirs?
