when does the next justice league trailer come out
â DC (@DCComics) November 14, 2016. From the sound of it, a second Justice League trailer is just on the horizon. The biggest question is when exactly viewers will be able to check it out.
That being said, Justice League is set to open on November 17, 2017, and a second JL movie is down for June 14, 2019 -- though that date isn't exactly set in stone. So far all of the DC movies have been rated PG-13, and we don't expect the Justice League movies to be any different.
