I have been thinking about this for a while and quite honesty it's a good idea and would really make more people know about the DCU..as for the movies that should come out after New 52..well
New 52: The Rise of Baz
This movie details Bz's orgin and all the events that happened in the Rise of the Third Army..the team that is working on this movie are the same ones who worked on the Green Lantern Animated Series
New 52: Court of Owls
This is the Batman New 52 Movie and it details with him having to take on the deadly force that is known as Court of the Owls.. personally i really hope that would happen though..it could be really freaking epic..Made by the same team as the Dark Knight Returns Movie
New 52: Justice League
This Details the first ever meeting of the Justice League and their conglit with the terror known as Darkseid..will be the first New 52 Movie to set up the universe and will be worked on the same people who did the Justice League Doom Movie.
New 52: Aquaman: The Others
This details with Aquman trying to find out what really happened to Atlantis the day it sank..Aquaman also has to deal with the greatest enemy yet..the awesome villain known as Black Manta..is being worked on the same people who did Young Justice Invasion
New 52: Shazam the Movie
It details Billy Batson's orgin from a punk into one of the greatest heroes ever known but he is very reluctant to carry out this task but he must in order to save the world from Black Adam who has been gathering the sins in order to desultory the world.
New 52: Earth 2
It details with the origins of Alan Scott Green Lantern and Jay Garrick Flash, Khald is mentioned and Hawkgirl is the main character..Solomon Grundy is the main villain as he attacks America..and together everyone has to team up to stop him.
