Just three years ago, it seemed like the possibility of getting an Unbreakable sequel was a pipe dream. But then in typical M. Night Shyamalan fashion, Split had a twist ending: that it existed in the same world as Unbreakable. Now we're just weeks away from the sequel to both movies, Glass, hitting theaters. January isn't usually a banner month for movies, but Glass is currently predicted to kick off with an impressive debut, potentially upwards of $70 million.

Early tracking places Glass at opening between $70 to $75 million on the Martin Luther King holiday weekend, although some are being more conservative with their estimates and placing it around $50 million during its first four days, according to Variety. Even if Glass falls on the lower side end of the tracking spectrum, it would still result in Glass being one of the most biggest Martin Luther king weekend openings of all time. 2015's American Sniper holds the record with $107 million, but Glass could knock 2014's Ride Along and its $48 million from second to third place.

It should be noted that Glass has absolutely no opening weekend competition. A Dog's Way Home and The Upside are premiering the week before, and movies like Aquaman, Bumblebee and Mary Poppins Returns might still be pulling in some stragglers, but Glass basically has an extended weekend to itself, which explains why it'll likely have a remarkable opening.

With a $20 million budget, Glass is actually one of the pricier movies from Blumhouse, a production company that likes to keep its budgets small. Nevertheless, should the opening weekend estimates hold up, Glass won't have any issue making a profit. The bigger question is how it will hold up against Split, which was made off $9 million and collected $278.5 million worldwide. Unbreakable had a much larger budget of $75 million since it was distributed by Disney back in the day, and it ended its theatrical run with $248 million worldwide.

Serving as the final installment of the Eastrail 177 trilogy, Glass will see Samuel L. Jackson's Elias Price, a.k.a. Mr. Glass/The Mastermind, and James McAvoy's Kevin Wendell Crumb, a.k.a. The Horde joining forces, with Price specifically taking an interest in Crumb's 24th and most dangerous personality, The Beast. It'll be up to Bruce Willis' David Dunn, a.k.a. The Overseer, to stop them before a lot of people die. The main cast also includes Sarah Paulson as Dr. Ellie Staple, Anya Taylor-Joy as Casey Cooke, Spencer Treat Clark as Joseph Dunn and Charlene Woodard as Mrs. Price.
