While The Dark Tower has missed a couple of high profile releases already this year, Guardians of the Galaxy Vol. 2 gets the summer movie season underway this Friday, so if The Dark Tower trailer ends up attached to that, at the very least the trailer will get in front of a lot of eyeballs, which will be important for making people aware the movie is coming.
Due to the now compressed timeline that the movie is working with, we’d fully expect to see the trailer attached to films as early as this Friday, potentially with an online release sometime during the coming week.
