Edmond O'Brien is Winston Smith. Jan Sterling is Julia. This movie did a pretty good job of depicting the story. However everyone stayed fully clothed and Goldstein's name has been changed to protect the innocent. And O'Brian becomes O'Conner.
In a society that has eliminated many imbalances, surplus goods, and even class struggle, there are bound to be deviates; Winston Smith is one of those. He starts out, due to his inability to doublethink, with thoughtcrime. This is in a society that believes a thought is as real as the deed. Eventually he graduates through a series of misdemeanors to illicit sex and even plans to overthrow the very government that took him in as an orphan. If he gets caught, he will be sent to the "Ministry of Love" where they have a record of 100% cures for this sort of insanity. They will even forgive his past indiscretions.
