There is a lot of interest in Zack Snyder's upcoming Justice League movie and so there are a lot of people trying to get as much information as possible about it. The result is a lot of rumors, many of which turn out to be false. Zack Snyder just put one of those to bed. Recently, it was posted online that Justice League had an official run time of 170 minutes. Somebody pointed out on social media that it was odd that the movie had an official runtime, considering the fact that it had not yet been completed. Snyder explained that, of course, such a thing was impossible, but it was the way he said it that was beautiful. Check it out.
At some point, you have to figure Zack Snyder just gets tired of all the constant rumors, and even more so the ones that have little to no basis in reality. He could have just come out and said the rumor was untrue, but there's a bit more snark than that here. He clearly needed to vent a little.
Nobody was quite sure where IMDB would have gotten the runtime number that was previously posted and now it seems that Zack Snyder is among the people who have no idea where the number came from. For the record, the 170-minute runtime has been pulled from Justice League's IMDB page. No number is up in its place and so we're back to no guess at all.
Nobody is expecting Justice League to be a short movie. Batman v Superman: Dawn of Justice clocked in at two and a half hours long and it only had to balance two superheroes with a cameo from a third. The Avengers came in at two hours and 20 minutes, but that movie had the benefit of having already introduced the majority of its characters, so it could sail through that part fairly quickly. From everything we know, Justice League is going to have to fully introduce Flash, Aquaman, and Cyborg, while also convincing them to join the team. A nearly three-hour movie may seem long, but it's hard to believe that the film won't begin to approach a runtime like that considering everything that needs to happen.
Even if the final cut of Justice League is something closer to 2.5 hours, we can expect a three-hour long extended edition with deleted scenes more than likely to come along when the movie is released next year on Blu-Ray. There will almost certainly be parts of the film that will need to be cut in order to make the runtime easier to deal with for the audience that Snyder will have wanted to include. Although, many believed that the ultimate edition of B__atman v Superman: Dawn of Justice was a significant improvement over the theatrical release. Perhaps Warner Bros. will take note of that and allow a longer cut of the film to be released in theaters if that's what Zack Snyder would like to do.
