Avengers: Infinity War - Directors Tease Thanos' Vault

Marvel's favourite directing duo, The Russos, have previous with teasing on social media. For the past two years, they've used a Twitter account to essentially troll MCU fans by posting provocatively obscure images - all presumed to be from upcoming movie projects - and they've come back for another round with a mysterious shot that looks suspiciously familiar for once.

The latest teaser image shows off far more than past teases, and appears to show the other side of Thanos' heavy duty vault that was shown briefly at the end of Avengers: Age Of Ultron. The shape certainly looks like it fits, anyway...

What we saw of the vault at the end of Ultron showed the same sort of circular door and a series of complex locks (suggesting Thanos worries about others stealing his Gauntlet, presumably). But then again, why it would even be included in the film when he's already retrieved the Gauntlet remains to be seen.

Or maybe the Russos are simply doing what they always do - having fun at the expense of the sanity of those fans looking to find extra meaning in their images...
