Marvel’s Skrull Retcon Ruined Endgame’s Deepest Improv Moment

Marvel Studios’ biggest Skrull plot twist in Secret Invasion ruins Avengers: Endgame‘s deepest improvised moment. In 2019, the Marvel Cinematic Universe finally wrapped up the Infinity Saga with the Joe and Anthony Russo blockbuster. To say that there was so much pressure to stick the landing with Avengers: Endgame would be an understatement, considering that it would significantly impact how the MCU’s first decade would be remembered. Despite this, the Russos still gave the actors creative wiggle room for improvisation, and many of those unscripted moments ended up in the film.
