Gal Gadot is bringing Wonder Woman to the big screen in the 2016 film Batman V Superman: Dawn of Justice as well as starting production very soon on the Wonder Woman solo movie. However, before the DC Extended Universe came together, the Amazon Princess almost made it the big screen a few years ago. Megan Gale was supposed to play Diana Prince in George Miler’s Justice League Mortal film that ended up not happening for several reasons.
While it was known that costumes have been made and that actors had been tested for them, most of them have not been revealed to the public. However, photographer Marc Rogers recently posted what appears to be concept art of Gale as Wonder Woman. The costume seemed to have a modern tone to it as well as paying some homage to past versions of the Wonder Woman costume.
