Kids who tuned in to watch the live-action Tom & Jerry got treated to a leaked version of the highly anticipated Justice League Snyder Cut.
“Zack Snyder’s Justice League was temporarily available on HBO Max and the error was addressed within minutes,” the streaming service said in a statement.
The Justice League error first came to light when Doug Bass of Charlotte, North Carolina, noted it on Twitter. Bass told The Hollywood Reporter he attempted to watch Tom & Jerry, but instead was able to access one hour of Justice League before it was cut off. When Bass tried to restart the film, Tom & Jerry played as it should have, suggesting that users were able to cache a certain amount of Justice League in the window it was available.
Several other users have noted this error, and THR was able to access Justice League via HBO Max. When THR attempted to play Tom & Jerry, first an error message appeared, and then Snyder’s Justice League cut began. When pausing the film, a message said the user was watching Tom & Jerry.
Some users shared screenshots of Justice League, but on Monday night, Twitter sent takedown notices on behalf of Warner Bros. to those who shared screenshots.
For Bass, seeing a bit of Justice League was a nice surprise on a Monday afternoon.
“I just wanted to put on Tom & Jerry for background noise while I worked, and instead I watched an hour of an amazing movie,” says Bass.
