This is part of the DCCU that I would make if Warner Bros suddenly put me in-charge because they have had a board meeting where someone says take a look at these rather poorly written story-lines I found on CBM and they all decide "Yes, we put this man in-charge."
It follows up my Batman vs Superman: http://www.comicbookmovie.com/fansites/Guido/news/?a=93769

This movie should be done in a big fantasy, ancient Greek style way. Like 300. In fact if a Wonder Woman movie could be like 300 that would be awesome, so I would happy with Zack Snyder directing just get someone who isn't David Goyer to write the script. Obviously not the story-line of 300, just visually. Anyway, here's the fancast
Diana Prince/Wonder Woman: Gal Gadot has been chosen as Wonder Woman already. To be honest this is the only casting decision for Batman vs Superman that I don't like. This is because I have not scene her give any solid acting performances (Fast and Furious definitely doesn't count.)
If it was my choice I would go for Gemma Arterton. She has taken on many roles where she plays a pretty badass girl in a historical or ancient setting: Clash of the Titans, Prince of Persia and Hansel and Gretel. Also she looks a lot like Wonder Woman.
Ares: Karl Urban because Dredd. He showed us how awesome and (I use this word too much) badass he can be. Also in other films he has proved that he has range.
Zeus: Liam Neeson because he is so authoritative and (searching for synonyms of badass) Chuck Norris like (that was the best I could do. Also he has already been Zeus so he knows what he is doing and already has a costume.
Hippolyta: Lucy Lawless, although a bit young for Wonder Woman's mother she is a very good actress and would suit the role, just watch Spartacus. I considered Lynda Carter but then realized she isn't such a great actress, maybe give her a cameo.
Steve Trevor: Alex O'Loughlin because he would be convincing as a jet pilot, military man dude (see Hawaii five-0). He needs to be manly so he isn't Wonder Woman's damsel in distress (see Hawaii five-0). Also he has experience playing a character called Steve (see Hawaii five-0).
Just a word on the costume, I want to see it look like Greek armor with a skirt and for Wonder Woman to have a sword and shield. My story-line will be coming soon.
