According to Comic Book Resources on April 9, "Man of Steel's" screenwriter David S. Goyer gave his honest opinion about having a cohesive DC Cinematic Universe like that of Marvel Studios. However, he feels it's simply "too early" to have such an idea in place at this time.
With "Marvel's Agents of S.H.I.E.L.D." having already tied in with "Captain America: The Winter Soldier" and "Thor: The Dark World", fans are wondering if the the ever popular CW's "Arrow" and its spin-off "Flash" will tie into the next "Man of Steel" sequel. Goyer, who will also be producer of the upcoming NBC's "Constantine", mentions there's been conversations among Warner Brothers Studios cohorts about having the DC Universe having a close-knit connection other comic book movie characters, but the director/producer feels that one should not try to "emulate" Marvel Studio's Cinematic Universe either.
It is notable that both Marvel Studios and DC are competing with each other when it comes to their opening dates of their films, "Captain America 3" and "Batman vs. Superman". It's a game of chicken between the two and some fans contend who will easily just step aside on that day in order to be profitable. Even to this very day, Marvel Studios refuses to budge from the opening date.
Goyer's "Man of Steel" film also got some criticism in regards to how the "Man of Steel" film was concluded. In fact, even the dissatisfied writer of one of the superman comic books Mark Waid was emphatic about the fact that it goes against the "hero's code".
On the other side, other DC Comics projects are in the works such as "Gotham" which mainly focuses on a young James Gordon , played by Ben McKenzie, who later becomes the city's commissioner. Also a "Sandman" film is in process as well as an adaptation of "iZombie" by Vertigo Comics.
Zack Snyder's "Batman vs. Superman" is scheduled to open along with "Captain America 3" on May 6, 2015.
