Want to bring him back, just so he can make a cameo? Have Pine's Kirk discover a holo log he left to himself, to be opened at this particular time and date.

Problem solved.

You people keep writing different versions of the same story. Susan's absence in The Last Battle has exactly zero to do with "sexism." Please make an effort to actually read the books if you are going to continue to write articles.

Several characters, both male and female "age out" and are kept out of Narnia throughout the story, including Digroy, Polly, and even Peter, the High King. Peter is also kept out of Narnia in "The Voyage of the Dawn Treader" because, like Susan, he has grown up enough that he begins to think that Narnia was just a childhood fantasy.

Lewis originally wrote these books for his niece, Lucy Barfield, and Narnia is a metaphore for faith.

By the time of "The Last Battle," Lucy is about or close to 18, which is an adult by post WW2 standards. Also present in Narnia are Jill Pole, who is about 20, and Aunt Polly, who is MUCH older. So we have three adult females, and four adult males that return to Narnia just as that world is ending.

Lewis wanted to write a story about faith, and he needed a character who loses hers. He picked Susan, and he lays the groundwork for this all the way back in "The Lion the Witch and the Wardrobe," and then returns to that theme in both "Prince Caspian" and Dawn Treader. However, it is made clear that there is still a place for Susan in Narnia if she ever manages to get her faith back.

You keep inserting controversy where none exists because it is that important to you that there is a place in this story for Saoirse Ronan that you would have Gerwig completely change the story. There IS a place for her. She's old enough now to play Jadis or the Lady of the Green Veil. Leave Susan alone. She's perfectly imperfect exactly as Lewis created her.
