I believe the movie "Forrest Gump" has one of the best character developments in cinema. The character of Forrest Gump, portrayed by Tom Hanks, undergoes significant growth and transformation throughout the film. His journey from a young boy with physical disabilities to a successful and influential man is truly remarkable. The reason I find Forrest Gump's character arc compelling is because it captures the essence of resilience, kindness, and the power of perseverance. Despite facing numerous challenges and setbacks in life, Forrest remains true to himself, maintains his innocence, and touches the lives of everyone.
