A Justice League movie has been off and on for years now, yet George Miller, the more frequently on again and off again director of the proposed movie, told MTV:
I’m still attached to the film. Warner Bros. is waiting to develop the other characters a little
bit and then bring Justice League together. After the success of
[The Dark Knight], it’s well known that they will develop the other
characters and then bring them together in Justice League. That’s a
fair way down the track.
So break out the popcorn and soda! Just put them back. Immediately. Then break them out again many years later.
