No, it's not. The Medium movie is a fictional creation, not based on real events or people.
The Medium is not a true story. It's a work of fiction that was developed by the creative minds of the filmmakers to entertain the audience with a fictional narrative and imaginative elements.
The Medium movie is purely fictional. It doesn't draw from any real-life incidents or true stories. Instead, it offers a made-up plot and characters for viewers to enjoy and immerse themselves in a fictional world.
