I want to know the answer to the following question:
How many Imax screens showed Spectre on its opening weekend 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?
