Now that "The Batman's" production has been pushed back into 2018, Warner Bros. is turning their attention elsewhere in hopes of getting another film into production alongside "Aquaman" by the year's end.

"The Batman" director Matt Reeves is still in post-production on "War for the Planet of the Apes" for Fox, and rumors have postulated that the talent involved with the upcoming Bat-film want to start from scratch on the script. That leaves the "Aquaman" as the only DC Extended Universe film set to enter production this year. However, that could change. According to Variety's Justin Kroll, the studio is currently looking at a few of their other previously announced projects with the hopes of putting one into production later this year.

With BATMAN likely shooting in 2018, WB still would like one more DC property to shoot this year other than AQUAMAN

The 5 films being considered are SIRENS, FLASH, LANTERN, SQUAD 2 and DARK UNIVERSE.

That said if scripts aren't ready to go, studio is content just shooting AQUAMAN this year till films are ready to go

The Harley Quinn-led "Gotham Sirens," "The Flash," "Green Lantern," "Suicide Squad 2" and "Justice League Dark" are just a few options WB has. Out of those options, the obvious choice would be "Gotham Sirens," as not only does that film already have a star, but it also has a director and a writer attached to the project.

As for "The Flash," that project recently lost its second director not too long ago, and it was also revealed that the studio was set to order a page-one rewrite on the film. Should that film somehow enter production this year, it could be another case of "Suicide Squad," where director David Ayer had a short amount of time he had prior to production.

"Green Lantern," is probably the least likely of the above listed. That project has no talent attached to it yet, although Armie Hammer's name seems to be continually be tossed around for the role of Hal Jordan.

Outside of "Gotham Sirens," the only other true options for this year would be "Suicide Squad 2" -- which just landed a new writer and has had Mel Gibson in talks to direct -- and "Justice League Dark," which has already secured a director with Doug Liman and has a script penned by Guillermo del Toro.

Of course, just because Warner Bros. would like to see a second film go into production this year, that doesn't mean it will definitely happen. Nevertheless, filming on "Aquaman" -- which will be directed by James Wan and star Jason Momoa -- is set to begin filming this spring, though the release date has been pushed back from October 2018 to December 2018.

Opening June 2, "Wonder Woman" -- the next DCEU film -- stars Gal Gadot, Chris Pine, Robin Wright, Lucy Davis, Lisa Loven Kongsli, Danny Huston, Elena Anaya, Ewen Bremner, Saïd Taghmaoui and David Thewlis.
