Jason Momoa was acting long before HBO's Game of Thrones made its debut, but it was his role as Khal Drogo that boosted the man's career to where it is today. After watching the show, it's easy to see why: Khal Drogo wasn't just an iconic character, but one of the best reasons to watch the first season of Game of Thrones. While his time on the show was sadly short-lived, it ended up having a huge impact on Momoa's career.

With every casting comes an audition, but only a fraction of these early tests are ever made available for the public to see. That wasn't the case with Momoa's audition for Game of Thrones, and after watching the short video, it's easy to see why the actor was chosen for the role. You may want to turn the volume down a bit, it's pretty intense.

It's not a long audition, but it's a powerful one. While it might look like Momoa has lost his mind at first glance, the actor is actually performing a 'haka,' or a traditional New Zealand war cry. It's far more intense than any monologue could ever hope to be, and given the performance, Momoa as Khal Drogo just made sense.

The clip isn't new - it originally appeared on YouTube back in 2012 - but Momoa's more recent casting news has brought the video back to the forefront. Just a few days ago, Momoa confirmed that he had been signed on to appear as Aquaman in DC's upcoming film universe, starting with Justice League (though rumors say he may debut in Batman v. Superman). Again, it seems like a fantastic fit; if Momoa can play Aquaman as well as he did Drogo, the role could be career-defining.

And who knows - maybe it won't be too long before we see Momoa's audition tape for Aquaman...
