Josh Brolin, who plays Thanos in the upcoming Avengers film, has responded to the outrageous Ant-Man fan theory which has been making the rounds on social media.

If you have been excited about Avengers: Endgame, you may have come across a particularly inventive theory on how the smallest Avenger could take out Thanos without even fighting.

The theory postulates that Ant-Man could shrink down and approach Thanos… from the rear. Once nestled securely in Thanos’ butt, all Ant-Man would need to do is hit the gas, turn himself giant-sized, and Thanos would meet a particularly messy end.

In response to the theory, Brolin made a post on Instagram, revealing just how the Mad Titan would flush the competition, should the need arise. “The tension around what ‘Endgame’ is going to bring,” Brolin said, “I can feel it, as you can see. Can you?”

If Ant-Man doesn’t give Thanos the runs for his money, there are any number of ways the Avengers can take down the Mad Titan. For more on Avengers: Endgame, be sure to check out our video on who the strongest Avenger is, and check out the cool new movie posters for China and Russia.
