Based on the book Final Vision: The Last Word On Jeffrey MacDonald by Joe McGinniss, the new Investigation Discovery true-crime movie Final Vision centers around Jeffrey MacDonald, better known as the Green Beret Killer, a man convicted of murdering his pregnant wife and two daughters in 1970. While he ended up being convicted, MacDonald pleaded not guilty to the murders, claiming four intruders attacked him and his family after he fell asleep in the living room. Because they immersed themselves in this project for so long, we ask stars Dave Annable and Scott Foley where they stand on MacDonald’s guilt. Foley, who plays MacDonald, is convinced of his innocence, while Annable, who plays McGinniss, thinks he’s guilty.
