We also saw Jurassic World: Fallen Kingdom and Mission: Impossible — Fallout come out, among other big releases.
This spring and summer also saw a ton of tentpole movies get released, least among them Avengers: Infinity War.
More people headed to the movies during the summer this year compared to 2017.
For example, February is often a dead month at the movies, but last February when MoviePass still had a high subscriber rate, both Black Panther and Fifty Shades Freed came out and did very well at the box office.
