"On your left." Those three words are part of the DNA of every Marvel fan and moviegoer who witnessed Avengers: Endgame's iconic portals scene. But it was almost very different. Now, though, Endgame co-director Joe Russo has revealed the original plan for the climactic moment – and how they fought "for months" to change it in post-production.

Avengers: Endgame saw Hulk putting on the Infinity gauntlet and snapping the blipped characters back to life. But unless the actual moment, nobody was sure how their return would be shown onscreen. Directors Joe and Anthony Russo claimed the portals scene underwent a lot of changes in the post production.
