Avengers 4 - 5/3/19
Star Wars 9 - 12/20/19
According to Box Office Mojo, and I don't know how up to date this is, Masters of the Universe opens 12/18, the film version of the musical Wicked will open 12/20 and on Christmas Day, The Call of the Wild, Superintelligence and SPA Animated Franchise II (whatever the hell that is) will open. This of course, being 18 months out, is subject to change, but unless Masters of the Universe is any kind of good, there's no real competition at the moment for Star Wars in the first week. Counterprogramming with Wicked and Superintelligence, sure. But no competition.
