http://forum.newsarama.com/showthread.php?t=100246 Some clearing up with the Goyer situation. Although WB is not looking to make a "comedy" they do want something lighter in tone than Batman Begins and Superman Returns. I would agree with this because ideally The Flash *should* be lighter in tone than a Batman film and SR does suffer from being somber.
As for who would be best for Wonder Woman, offhand I'm not sure but I was never comfortable with the choice of Wedon. From day one he said he didn't like her costume and I really don't like his style of writing dialog.
