Source Given that they waited till now I think that Fox either doesn't have the rights they claim to have, or they want to settle for more money than the judge is likely to award them. Though I can see the Warner Bros. lawyers arguing against the injunction for several reasons, with one of them being that the injunction will hurt Fox's reputation. "Your honer, we feel that you will be hurting the plaintiffs if you give them the relief they request"
I didn't know much about Watchman, but I now have read a little of it. I think the movie could be good. This is almost as messed up as Fox News.
I never read the comic books, but when my cousin told me all about it, I was really intrigued. The movie looked good, but from the trailer, couldn't tell if the movie did the comic book justice. It would be sad for this movie to not be released.
