Some users logging in to HBO Max to watch Tom & Jerry: The Movie got a bit of a shock. Some of those that started the most didn’t see a cartoon cat and mouse battling to the death. Instead, they were met with an accidental showing of Zack Snyder’s four-hour cut of Justice League–a movie that is not out until March 18. This news comes from The Hollywood Reporter, which noted images from the movie appearing on Twitter.

While several people online noted that they were able to access the film, and THR even confirmed it was able to access the film, it appears the problem has since been fixed. So if you were one of the few that got to watch even part of Zack Snyder’s Justice League, consider yourself lucky.

For the rest of us, there are only 10 more days of waiting before you can see the movie properly. In the meantime, several character trailers are being released, covering each member of the superhero team. Thus far, Batman, Superman, Wonder Woman, The Flash, and Aquaman have each gotten a character spotlight, with only Cyborg left to go.

We already know quite a bit about the Justice League, if you want to be fully prepared for the film. Snyder has revealed the six chapter titles within the lengthy film, while also explaining why he decided to include Jared Leto’s Joker in the project and how many versions of his cut will exist.

Zack Snyder’s Justice League will be on HBO Max on March 18.
