One of the many fascinating things about The Prisoner is that no-one knows what order the episodes should be watched in. There is, however, a consensus on two things. Firstly, they should not be watched in the order they were made, and secondly, they should not be watched in the order they were broadcast.The order used for this list of The Prisoner episodes is the order of initial UK broadcast, also used on most DVD issues. This order causes some characterisation and thematic inconsistencies and there are other potential episode orders suggested by fans and by Patrick McGoohan's Word Of God.
