As you'll see from the clip, below, the cast will be in New York City for the global premiere, but after that, who knows? Seriously, nobody does. That's because the world premiere tour - which is called the X-Men X-Perience - will have a twist.
Although the premiere dates and locations have been announced...
Saturday, May 10, New York Global Premiere
Monday, May 12, London
Tuesday, May 13, Moscow
Wednesday, May 14, Singapore
Thursday, May 15, Sao Paulo
Friday, May 16, Melbourne and Beijing
...it hasn't been announced which actor will appear in which city.
So, if you want to attend the premiere in say, Sao Paulo, you won't know if Hugh Jackman, James McAvoy and Michael Fassbender, Jennifer Lawrence, Patrick Stewart, Ian McKellen, Nicholas Hoult, Ellen Page, Peter Dinklage, Shawn Ashmore, Omar Sy, Daniel Cudmore, Evan Peters, and Fan Bingbing, will actually turn up.
According to Time Out Melbourne, however, Peter Dinklage, Fan Bingbing, and of course, Australian Hugh Jackman will be appearing at the Melbourne premiere.
Can't make it to any of these cities? The cast will be answering questions that you can send to them on Twitter via #XMenLive.
Check out the announcement from Fassbender, Jackman, and McAvoy.
