CinemaCon 2017 - Warner Bros. Pictures Invites You To 'The Big Picture', An Exclusive Presentation Of Our Upcoming SlateJason Momoa just called "Justice League""kind of the greatest movie in the world," but fans should not expect to be as long as "The Greatest Story Ever Told."

The Rumor Mill got itself churning during this week's CinemaCon, suggesting "Justice League" will be 170 minutes long. That would make it 20 minutes longer than director Zack Snyder's previous DCEU movie, "Batman v Superman: Dawn of Justice," which was 2 hours and 31 minutes -- not including the extended cut. IMDb now has "Justice League" listed at 2 hours and 50 minutes, but that's possibly born from the reports now circling.

According the TheWrap, "an individual with close knowledge of the project" said the film is not 170 minutes long. The source said the filmmakers aren't even close to knowing the final running time because the movie isn't done yet. It won't hit theaters until November 17, so the final cut is far from set.

Warner Bros. just had a panel at CinemaCon in Las Vegas, showing off footage and previewing what's ahead in the DC Extended Universe. Momoa left directly from there to film "Aquaman" with director James Wan, and he praised his "Justice League" cast and director in a photo on Instagram:

"Me and my brothers Minus my beautiful sister @gal_gadot can't wait to see u and your OHANA I f*cking love my job. JL. Mahalo Zack for believing in me. You are a genius I can't wait for this movie I'm off to make Aquaman with @creepypuppet can't wait. Love to all my friends I'll miss you see u in my dreams. OHANA aloha j."

"Justice League" opens November 17, and it may be a while before Warner Bros. reveals the official final run time.
