$200 Million in three weekends will outpace Titanic. If that happens, that will be amazing.
Not really. Titanic had a titanic total gross because it defied the normal box office pattern and kept generating high ticket sales week after week after week. Other blockbusters follow the normal pattern of a huge opening followed by a predictable tailing off.
For example, Lord of the Rings - Return of the King, Spider-Man, and Star Wars - The Phantom Menace all racked up over $100 million on their first weekends and over $200 million by the Monday after their second weekends. It would not be at all surprising for The Da Vinci Code to pull in similar grosses.
