Avengers: Infinity War was the biggest crossover event any Superhero film has ever had as it brought in the most number of Superheroes at once.
Previously Civil War was able to make great use of the characters it brought in, but because the number of heroes was almost doubled in Infinity War, so it was obvious that all the characters will not get to shine as much as they could have.
But still, the Russos did incorporate all of them as well as they could and made great use of some characters like Rocket, Groot & even Mantis.
If you think about it, Rocket & Groot obviously did not get a lot to do in the film, but they did really have a crucial role to play, and without them, the film could have actually gone differently.
Rocket was the pilot who assisted Thor on the journey to Nidavellir, and that is about it for him, but from there we see Groot make the very crucial assist, which was to give a handle to the Stormbreaker. Apart from that, he largely played his video game and had a couple of scenes in the final war of Wakanda.
But originally, there was another major sequence planned for Groot and he would have helped Eitri as well. When we see Eitri for the first time in the movie, we find out that Thanos killed off his fellow dwarves and he ruined Eitri’s hands so he could not make another Infinity Gauntlet in the future.
So, in the early drafts of the script, Groot would help Eitri out by becoming a sort of exo-suit and do whatever Eitri needed to.
Revealed in The Art of Avengers: Infinity War by concept artist John Staub that Groot had a whole helping montage which would have added to the funny moments of the film. Here’s what he said:
“The original scene in the script just said ‘Groot helps Eitri,’ giving me a lot of freedom to come up with something interesting and unique. I was handed the script with the scene and was trusted to come up with something cool. Minimal direction was given to me, which left room for my ideas to come through. We already know that Groot can extend and reshape his arms when he fights I thought it would be cool to see him use them in a more utilitarian manner, like to help pick things up or to build something. I also thought it would be kind of cute to see Groot hanging on the back of Eitri like a backpack as they banter to each other about their situation I set up the scene in a simple way that focused on showing how Groot would help Eitri–nothing to dynamic or intense, something more straightforward. It was really fun to draw this scene thinking about the different ways Groot would act almost like a living exosuit and help Eitri do his work.”
While all this would have been fun to watch, it might have added to the screen time of the film which was already pretty limited. So it is okay for this scene to be skipped and altered.
The ending of the film was pretty emotional as we did not expect teenage Groot to go down. He could have added a lot of fun in the next film. But for the way the scene was written, it made sense for him to be dusted, as that would make the biggest impact upon Rocket.
So we are looking forward to the return of Groot in Avengers 4. Hopefully, he gets to do something significant in the film when he returns from the dead. Avengers 4 comes out on May 3.
