Working titles are generally used to disguise the production of a high profile film. Batman Begins’ working title was “The Intimidation Game” and The Dark Knight worked under “Rory’s First Kiss”. According to the latest issue of Production Weekly, The Dark Knight Rises will be known as “Magnus Rex” when it goes into production this May.

Fun fact: Magnus is the name of Christopher Nolan’s son. We’ll find out soon if “Magnus Rex” is in fact the working title for The Dark Knight Rises.

Update: Production Weekly has updated their post. It looks like “Fox Hills Green” is another possible working title.

Update #2: We’ve heard that The Dark Knight Rises would be shooting in NYC this week, and it looks like that’s confirmed. According to a document on NYC.gov, “Magnus Rex” will begin shooting today and go until the end of the year. I think we have an official working title!
