Yesterday we learned that Warner Bros. was moving forward with a Justice League movie, and that they hired Gangster Squad screenwriter Will Beall to write the script. That same report from Variety also mentioned that the studio hired another screenwriter to take a crack at a Wonder Woman movie. That writer is Michael Goldenberg, who also worked on Green Lantern, so that doesn't spark any confidence. The script for Green Lantern sucked, but he's also working on the sequel for that as well.
Wonder Woman is also a property that the WB is kicking their own ass over as Joss Whedon was working on the film at one point, and they ended up not following through with it. The studios just seemed to lack faith in Whedon until Marvel gave him a shot with The Avengers. He showed the world the badassness he brings to the table.
