In a major slip-up on Monday, Zack Snyder's Justice League was uploaded on HBO Max instead of Warner Bros' Tom & Jerry movie. 

Although the streamer did damage control almost immediately and removed Justice League and uploaded the right film, the gaffe was criticised widely on social media. 

Popularly called the Snyder cut, this version is billed to be starkly different from the 2017 film, and will begin streaming on HBO Max from March 18. 

"Zack Snyder's Justice League was temporarily available on HBO Max and the error was addressed within minutes," HBO Max said in a statement. 

The Snyder cut version of Justice League is one of the most anticipated HBO Max titles of the year. After helming Man of Steel and Batman v Superman: Dawn of Justice, Snyder left Justice League during post-production due to a family tragedy in 2017. The studio roped in Joss Whedon to do the post-production and oversee the reshoots. However, there was a strong speculation that Whedon changed the entire outlook of the film and it was nothing like what Snyder had envisioned for the movie. 

The theatrical release of the movie was followed by DC Extended Universe (DCEU) fans petitioning the studio to release the original cut of the film from Snyder. After years of such requests, Warner Bros finally announced last year that Snyder's version would come to HBO Max in 2021.
