The video has now been removed, though it stayed up for long enough that a LOT of people noticed how incredibly weird it was.
And because the internet is a strange and beautiful place, people decided to create masterpieces using the trailer.
All your favourite films are immediately improved with the addition of Tom Cruise's shrieks of terror.
If you weren't keen for The Mummy, maybe you'll be excited for "Top Gun: Cruise Control".
(I don't think anyone will like me if I make a "It's mu-mmy, Mario" joke here, will they?)
Imagine using it as an alarm. What a way to start the day!
While some think the trailer may have been leaked on purpose, most are just in agreement that it is one of the best mistakes in recent history.
That being said, it appears more people are keen for the movie after seeing the audio-less trailer.
The Mummy is scheduled to open in cinemas June 2017... probably with all the audio tracks.
