Josh Brolin had an incredible 2018. He starred in one of the highest grossing movies of all time as its iconic villain Thanos. He played the reluctant anti-hero as Cable in Deadpool 2. He even came back for Sicario: Day of the Soldado to reprise his role as the infamous Matt Graver. But his 2019 is already remarkable, well before the release of Avengers: Endgame.
