What happens when an extremely wealthy aristocrat dying of cancer undergoes a medical procedure that transfers his consciousness to the body of a healthy young man? Mayhem, naturally. Self/less opens in theaters today, bringing Ryan Reynolds and Ben Kingsley to a dramatic head in the most recent sci-fi thriller from Focus Features. Just when Kingsley’s character starts getting used to life in the fast lane (and the beautiful women that come with having a body like Reynolds’), the original young man slowly comes back—threatening Kingsley’s livelihood all over again.
