The Snyder cut is set to release on March 18th. Some viewers were instead shown the upcoming R-rated version of justice league.
Hbo confirmed that, yes, this did in fact happen. It’s unclear if this was worldwide, or if the Snyder cut only showed up in certain regions.
Fans were only to see about an hour of the four-hour long Tom and Jerry movie. It may have been just enough to traumatize kids whose parents were just trying to babysit them with cat-and-mouse hijinks.
Go to HBO and try to watch Tom and Jerry and the back out and try it again. The Justice league Snyder cut?.
