Warner Bros. and DC have announced 13 movies, not including its Vertigo slate, for the immediate future. They also have four different TV shows on the air, with more to come. The big question fans have is: How do these projects all tie together? Well, as DC creative chief Geoff Johns explains it, all of these DC movies and TV shows form a multiverse.Basically, The CW's The Flash and Grant Gustin's Barry Allen exist on a different plain of reality from Ezra Miller's version of the character in 2018's big screen standalone adventure The Flash.
