MAYBE Avatar 2? I mean thats a strong maybe. I don't see another star wars having this impact because the novelty will have worn off. I feel like Avatar 2 is the next event film on that level. Batman Vs Superman is big but its not this big and it doesn't have the benefit of this which is basically 2-3 weeks of people being on vacation with their families, etc. So there's a lot of going to the movies especially if you got kids and need something to shut them up for 2 hours
No love at all for the possibility that Infinity War will crush buildings?
