The Chronicles of Narnia, written by C.S. Lewis over six decades ago, captured the hearts of many with its powerful lessons and emotional undertones. Its known for defining themes of forgiveness, kindness, and bravery that run throughout each book. All four Pevensie siblings display these traits, also receiving grace and forgiveness as they make missteps throughout the series. Notably, Edmund Pevensie betrays his siblings in the first book, and yet he is welcomed back into Narnia with open arms. Greta Gerwig will likely dive deeper into this dynamic soon in the upcoming Chronicles of Narnia remake.
