O'Brien is an inner party member. He took part in the torture of Winston Smith. Winston Smith saw O'Brien as someone who also is resisting the government of Oceania. However, it is later revealed that O'Brien is actually working for the party, apparently faithfully. As a member of the inner party, O'Brien had the privilege of turning off his telescreen (Not quite sure. He might have done it once to trick Winston.)
Appearance[]
In the book, it was stated that O’Brien was despicably ugly, and also quite tall. No other physical description is given.
In the movie, it appears that he has a wrinkly face with white-grey hair, about the age of 40 or 50.
