Geoff Johns and Allen Heinberg Wrote the Screenplay.
Those who have had issues with previous DCEU movies could probably trace most of their issues with the movies back to the script. It has been said that David Ayer only had six weeks to write Suicide Squad, which isn't nearly enough time to do a proper screenplay for a movie of that size and scope. Hopefully, Wonder Woman won't fall into those same traps. One thing is for sure, the screenplay took longer than six weeks to write. The screenplay that ultimately wound up being used for the movie was written by Allan Heinberg and Geoff Johns. The former has mostly worked on TV shows such as Grey's Anatomy and The OC and the latter is the head of the DC Comics properties for Warner Bros., who just so happens to be a very highly-regarded former comic book writer.
The two of them together makes for an interesting pair. Given that this is the first movie that Allan Heinberg is credited with writing, Warner Bros. must have seen something in him. As for Geoff Johns, he knows the world of DC Comics very well, so having his input on the screenplay can probably only be a good thing. No matter how Wonder Woman ultimately turns out, it will largely be these two guys who are responsible for it, good or bad.
Gal Gadot is Back as Wonder Woman.
Despite the fact that Batman V Superman: Dawn of Justice really seemed to divide audiences, one of the unquestionable highlights was getting to see Wonder Woman make her big screen debut. Something that was 75 years in the making. Since the DC Extended Universe is a connected series of movies, it will once again be Gal Gadot portraying Diana Prince in the Wonder Woman solo movie. Even before her epic fight with Doomsday at the end of BvS, the 31-year-old actress had proved herself in big-budget action movies, starring in both Fast Five and Fast & Furious 6. For the most part, the reception to Wonder Woman's limited screen time in Batman V Superman: Dawn of Justice was very positive, so that should serve as some encouragement heading into the Amazonian superhero's first solo movie ever. There is a lot of excitement about his movie and a lot of that will rest on Gal Gadot's shoulders. No pressure.
