You know The Dark Knight is going to be huge when...
(a) You go to the local grocery store yesterday at around 1:00 PM and see a young gentleman wearing a suit and tie holding up a sign that reads, "I Believe in Harvey Dent," and who proclaims that we should all cast our votes for Harvey Dent to every passerby.
(b) You read that 89% of all Fandango ticket sales have been for The Dark Knight in the past couple of weeks.
(c) You call up the Metreon Theatre in San Francisco today and when you ask what time you should show up to get in before the crowd for the 1:30 showing, they tell you that a large line of people were literally encircling the building before the theatre complex opened this morning to see some kind of special sneak peak--which will show at 7:00 tonight, and that for the IMAX opening day showing, the man on the other end of the line tells you that you should arrive at least one hour before the showtime as the line will become quite long to get in. Guess I better take the 10:10 ferry rather than the 11:10. And bring a book. And pack sandwiches. (I later called and asked if one could just sit down and eat food on the floor in line, to which the man said in a weary voice, "Yes, you can--we don't encourage you doing that... But we won't tackle you down to the ground if you do." Ah, such a welcoming invitation!)
