I want to know the answer to the following question:
How much money did preview showings generate in the US and Canada?
All the background I'm provided with is that "In the United States and Canada, the film opened on 6 November 2015, and in its opening weekend, was originally projected to gross $70–75 million from 3,927 screens, the widest release for a Bond film.". Is that enough to answer the question?
