Why Hasn't There Been A Wonder Woman Movie?

Hello, everybody!
I just saw JULIE & JULIA (a terrific movie for foodies and non-foodies alike!) and have decided to join the blogosphere!
Having failed to attend the San Diego Comic Convention this year :( I wanted to share my ideas for the Wonder Woman movie! I have prepared a screenplay to make this happen!
The movie rights are held by producer Joel Silver (of MATRIX TRILOGY fame) and Wonder Woman is owned by DC Comics, a subsidiary of Time Warner. Joel Silver is trying to decide between a movie taking place in WWII or in modern times.
I believe that Wonder Woman is a timeless character whose adventures should be set in the present day! I also believe that the expense of setting the movie in the past will further delay bringing Wonder Woman to the big screen.
What actress should play Wonder Woman? Having just seen Meryl Streep play Julia Child like she was "found money", only a surpassingly excellent actress should be given the golden lasso. Eva Green (CASINO ROYALE, THE GOLDEN COMPASS, KINGDOM OF HEAVEN) has the bearing, the acting chops and the exuberance to bring this thoroughly modern Wonder Woman to vibrant life!
How long should the movie be? Bigger than BATMAN BEGINS, my friends!
The challenge with Wonder Woman is that she has a complicated background. How the Amazon culture works needs to be explained. How Wonder Woman was created by sacred clay needs to be shown. Finally, how Wonder Woman begins her mission for peace in the world. Those three things alone are one movie.
However, as the Wonder Woman animated DVD showed, that leaves hardly any time for Wonder Woman to get into costume and get down to business. That was the same problem with the first Christopher Reeves SUPERMAN movie: too much Krypton, not enough Metropolis Marvel.
Then, Wonder Woman's civilian identity (that of a "philanthropologist") needs to be established. Her first battle with the Cheetah (played by Alison Lohman, MATCHSTICK MEN, DRAG ME TO HELL) needs to take place. Her definitive fight with Ares (played by Russell Crowe, STATE OF PLAY, THE INSIDER, GLADIATOR) has to happen. These three things comprise a second movie.
So; like SUPERMAN and SUPERMAN II, or, more relevantly, like MATRIX: RELOADED and MATRIX: REVOLUTIONS; two films need to be made back-to-back and released within the same calendar year to control production costs, retain the top flight talent and to maximize the wonderment!
These two films shall be called WONDER WOMAN ARRIVES and WONDER WOMAN: AT LAST!
Is Steve Trevor (played by Daniel Craig, CASINO ROYAL, THE GOLDEN COMPASS, QUANTUM OF SILENCE) a credible love interest? No, and he never has been. In these movies, Steve is married to Etta Candy (played by Kate Winslet, TITANIC, LITTLE CHILDREN, THE HOLIDAY), with some interesting results. So a different man (Matt Damon, the BOURNE trilogy) with strong ties to Paradise Island; to Aphrodite particularly; needs to be introduced, serving as a bridge between her childhood in Themiscyra and her new life in Manhattan.
Why doesn't Wonder Woman get along with her mother, Queen Hippolyta (played by Helen Mirren, THE QUEEN, EXCALIBUR, STATE OF PLAY)? It's more than a generational thing, it's that thing between Ares and Aphrodite (played by Catherine Zeta-Jones, THE MASK OF ZORRO, CHICAGO) which finds Wonder Woman caught dangerously in the middle.
Did Aphrodite create the Amazons? In these movies, it is Ares who creates (then destroys) the Amazons, and it is Aphrodite who sequesters them away to Themiscyra. This helps to better clarify Wonder Woman's mission for peace.
Who built the incredible Visible Plane? As Wonder Woman's comic debuted in 1941, it makes sense that Amelia Earhart (who disappeared in 1938 and is played by Cate Blanchett, THE AVIATOR, BANDITS, ELIZABETH) would have been rescued by Aphrodite and brought to Paradise Island, where she then built the Visible Plane, which is a VTOL (Vertical Take Off and Landing).
Thanks for reading!
Tomorrow, I'll post more of the proposed cast and have other goodies! If any of you have seen JULIE & JULIA and enjoyed it as much as I did, please let me know! Be good!
