Shown as a full 2 hour opener in the UK, but in 2 parts for most other territories. Subsequent home media releases and repeats use the 2 part version (including now the UK). Two versions of the end credits for Part 1 also exist. Originally the credits for Part 2 were edited onto the point at which Part 1 ends (creating an inconsistency with the 'Cast in Order or Appearance' as well as omissions for those who did not appear in Part 2), but remastered home media versions have the credits playing over a freeze frame of the last scene (now with the correct cast also).
