There is also one scene where the voice of an actor is dubbed.
But the unfinished production cut did not stop fans from creating stills of the episode, which have circulated online.
The leak is thought to have come from a post-production studio given the episode's unfinished nature, and was shared by a group called "HOMELAND".
Showtime has not officially responded to the leak, although Deadline reports that the show's producer 20th Century Fox has got their antipiracy unit working on the issue.
