It looks like this new Justice League movie being developed by Warner Bros. is still up in the air. Will Beal is writing the script, and we've been hearing about the villain and characters that will be involved in the story over the last couple of months. Even though the movie is supposed to be released in 2015, there's still a chance that it won't happen. Before the studio makes a final decision on whether they will movie forward with the project or not, they're going to wait to see how Zack Snyder's Man of Steel does. According to Variety,
Stakes are high for "Man of Steel." Other than Nolan's Batpics, Warners has not been able to effectively exploit the DC library. Its 2011 "Green Lantern" underperformed, and a "Justice League" film wouldn't likely be in theaters before 2015, as Warner's top brass has indicated that they are awaiting the results of "Man of Steel," which opens June 14, before moving further ahead.
It makes me wonder if they are planning to hire Snyder to direct the Justice League if Man of Steel does well. There's been talk of him already helping out with the story. Maybe they're also waiting to see if they want Henry Cavill back to reprise his role in the movie if audience like what they see.
I hope Man of Steel ends up being a great film! I've been waiting for an amazing Superman movie, and I would love to eventually see a Justice League movie happen. It's ridiculous that it hasn't happened already, and if there's any time to do it, it's now... even if Man of Steel doesn't do well. Hopefully Warner Bros. eventually finds their comic book movie groove.
