As suspense builds for this week's release of Avengers: End Game, Josh Brolin has got fans all hot and bothered after sharing a pretty racy picture of his purple, muscly on-screen counterpart, Thanos - who happens to be butt naked.

Brolin shared the artwork on Instagram, writing: "Before the armor, a shower. #washingavengerscumoff #powerliftingantmansquish #APRIL26SPOILER."
