My Own Worst Enemy.
Possibly one of the strangest things I have ever watched. Henry is a consultant living a normal life with his wife, kids dogs and a mini van. Edward is a trained operative who speaks 13 languages, runs a 4 minute mile and is trained to kill. What do they have in common? They both share the same body. But when the technology that seperates them starts to break down these absolute opposites find themselves in each others livesl where they are dangerously out of their element. Christian Slater does a good job of playing the 2 characters and the conversation they have by messages show just how much they dislike each other.
Certainly worth a look
