Those 23 weeks only pertain to how long we know for sure that the film played in the US.
As for how many other countries it played in, well, we know for certain that it played in Argentina, Australia, Austria, Belgium, Bolivia, Brazil, Bulgaria, Czech Republic, Chile, Colombia, Croatia, Denmark, East Africa, Ecuador, Egypt, Finland, France, Germany, Hong Kong, Hungary, Israel, Italy, Japan, Lebanon, Malaysia, Mexico, Netherlands, New Zealand, Panama, Peru, Portugal, Puerto Rico, Russia, Serbia & Montenegro, South Africa, Spain, Sweden, Turkey, United Kingdom, Uruguay, and Venezuela.
One huge market that it didn't play in is China because they ban any and every movie that has anything to do with the supernatural.
