Mark Ruffalo’s birthday message to Chris Hemsworth comes from his personal Instagram, and includes two photos from the set of Avengers: Endgame.
Ruffalo is wearing motion capture pajamas in the shot, and has dots covering face in order for the cameras to properly capture each and every facial movement.
Marvel fans can re-watch Avengers: Endgame on Disney+.
And while security on Marvel movies are notoriously tight, it looks like Ruffalo still managed to sneak some photos while working on The Russo Brothers’ latest Marvel blockbuster.
