Changing subject (because shauner111 asked) I have seen a lot of people put Christian Bale as Batman on their list of the ideal jl cast. I hate to be the one that breaks it to most of you but Bale can not be Batman in a JL film without pretty much spitting on the Nolan movies. The JL film can not claim to be seperate from the Nolan films with Bale in them, nor can they claim to be in the same continuity. Which reminds me, after seeing Avengers for the 100th time today(they always show it at my job) I couldn't help but wonder why didn't DC and WB do this back in 2005? That way, we could've had Bale, Routh, and Reynolds in their respective roles along with Kate Beckinsale and Ryan Gosling as WW and Flash( I only used them because I remember a rumor that they were the front-runners for those roles at one point. Not my personal choices, but not bad either) and Idris Elba as Jon'zz.
As excellent of a job as Nolan did with Batman, DC/WB should have had more long term goals and built up for a Justice League film three/four years before Marvel got things moving with Iron Man.They had the chance. Now they have to play catch up.
