Some of the leaps of logic in Avengers: Infinity War may have rubbed some fans the wrong way, but as far as the characters went, the writing team wanted to make sure that these characters were acting in ways that seemed natural — even if they were going to have to adapt to incredible situations.
Mild spoilers ahead for Avengers: Infinity War!
That rang especially true for Chris Pratt’s Star-Lord and Zoe Saldana’s Gamora. So they needed to bring in the big Gunns.
We knew Guardians of the Galaxy director James Gunn worked on Infinity War as an advisor to the GotG sections, finding music that would be appropriate and tweaking dialogue to fit the tone. But he also changed and signed off on — along with star Chris Pratt — a major decision by the gang’s leader. Here’s where things get spoilery.
Gamora knows the location of the one Infinity Stone that Thanos can’t find. She destroyed the map to the Soul Stone, but she could still lead Thanos there under the right amount of duress. She knows this and makes Star-Lord promise to kill her if Thanos ever gets ahold of her. Star-Lord says sure, but in the original script, when the time comes for him to pull the trigger, he can’t do it. That doesn’t sound like Star-Lord, or at least, it didn’t to Gunn and Pratt, according to Buzzfeed.
So they changed the script. Pratt pulls the trigger but only bubbles come out, thanks to Thanos' reality-warping abilities. “The more I think about it, the better it is that it got changed,” said screenwriter Stephen McFeely. It sets up yet another example of Thanos’ reality-bending powers and confirms that Star-Lord was willing to fulfill his promise and make the hard call.
“Thanos has that same choice later [to kill Gamora], and he chooses to do it and succeeds,” said McFeely. “Wanda has that same choice later [with Vision]. A lot of characters have really tough choices to make.” Making these tough choices in Infinity War, even if they’re going to get reversed (okay, especially if they’re going to get reversed), is the only kind of character development a film like this can give fans, simply because otherwise the characters haven’t adapted to the heaviness of the stakes.
