Avengers: Infinity War  

The Marvel Cinematic Universe (MCU) was over a dozen films that slowly built its climactic story. In Avengers: Infinity War, the stakes are arguably at their highest in any film thus-far. The heroes are trying to stop the villain Thanos from wiping out half of the universe’s population, but surely it being a superhero movie, the villain won’t actually win, right?

The film indeed ends with Thanos indeed snapping his fingers and turning half the population into literal dust, tugging at a lot of heartstrings, especially for an action film. As Tom Holland’s Spider-Man is fading away, he sadly says to his mentor Tony Stark, “I don’t want to go…” What most fans didn’t know was that the heartbreaking line was completely unscripted.
