The A-Force scene in Avengers: Endgame was originally a lot better. The scene in question finds Carol Danvers as she arrives on the battle field to help take down Thanos. In the final cut, we see Danvers take down the Mad Titan's ship with little to no problem as the rest of the female team take care of matters on the ground with the rest of the Avengers. It's an epic moment, no matter how you slice it, though some of the more negative fans have called the specific scene out as pandering. Regardless, screenwriters Christopher Markus and Stephen McFeely felt it would have been a missed opportunity had they not gone through with it.
According to The Art of Marvel Studios' Avengers: Endgame, the A-Force scene was going to originally include a lot more of a team effort to help Captain Marvel. In the lead up to the Carol Danvers standalone movie, Marvel Studios boss Kevin Feige promised that the character would be the most powerful character to be featured in the Marvel Cinematic Universe thus far. As it turns out, he was not kidding around. But, in Endgame, she was going to initially have some help. You can read an excerpt from the book below.
"Captain Marvel, being intergalactically powerful, would help take care of Thanos' ship, which at this point is just shooting blasts down onto the battlefield and making things really difficult for everyone, and she gets shot down on the ground. Pepper Potts, in her Rescue suit, sees that, rushes to her, and tries to protect her from another blast from the ship. So she raises her shield-protection powers and, as she's getting bombarded, calls to all the female Avengers to come help, and they all jump in around Captain Marvel in a circle... and they're all trying to fight off the Outriders and protect her.
Eventually, she comes to, realizes what's happening, thanks everyone, and then powers up full Binary. Pepper just goes, 'Do your thing, Captain.' And then she zooms into space and shoots through all the fighters and goes in and wrecks the big ship just like she does in the movie, taking the whole thing down."
Seeing the A-Force bond together to fight Thanos and his Black Order was already pretty satisfying, but seeing them work even closer together would have added a lot more time to the movie, which ended up at a little over 3 hours-long. Avengers: Endgame originally had a drastically different battle scene in more ways than one, but the Russo Brothers were able to pull everything off in a satisfying way for all parties involved.
The A-Force scene was groundbreaking for the MCU and many fans have been calling for a female-led Marvel team-up movie, which everybody from Brie Larson to Gwyneth Paltrow have also called for. "It really powerful and really exhilarating," Paltrow said, while also stating how it was a nice thing to be part of something so potentially inspiring to "young girls in the audience." That's really saying something since Paltrow herself doesn't even watch the MCU movies.
Will we see an A-Force movie in the MCU's future? Anything is possible, but if we do, it will more than likely revolve around some other characters. Regardless, Christopher Markus and Stephen McFeely made the right choice when they chose to include a version of the group on the big screen. While we wait to see what comes next in the MCU, you can take a step back and reflect on what has already happened with The Art of Marvel Studios' Avengers: Endgame, which you can purchase over at Marvel.
