I guess I'm the only one who thought of it as a black comedy. Doesn't Bill Murray's character kill himself several times? Hasn't he been trapped in the day for the equivalent of several lifetimes? Sounds amazingly awful.
apparently the scriptwriter had the Murray character visit the library each day and read one word on one page of a book, as a way of marking time in a world where nothing could be written down. The first drafts had him finish the library - thousands of years in the same day.
