The best sci-fi films ever made are mostly acknowledged for their visual effects at the Oscars. There are outliers, of course, as audiences saw when Michelle Yeoh won Best Actress for "Everything Everywhere All at Once" in 2023. When was the last time someone took home the Best Actor trophy for a sci-fi flick, though? It goes without saying that "Charly" isn't one of the more popular movies based on a sci-fi short story or novel. The film is largely forgotten, but it isn't the only Oscar-winning sci-fi flick that's rarely discussed today.
