Tardis:Cast lists

Story pages
As confirmed by forum discussion, cast lists shall give the name of the character, as listed in the credits seen on first transmission of an episode.

The character name shall be displayed exactly as in those credits, and in the order seen on original transmission. Thus, if characters are credited with only a first name, only that name should appear in the credits, linked by pipe trick to the full article name. For example, in the credits for The Hungry Earth, the character of Mo Northover shall be rendered thus:

Any actors credited on subsequent transmission, or in home video releases, that were not originally credited shall be placed in a special subsection which alerts viewers to that fact.

For audio stories, cast lists should ideally be taken from the back cover of the casing, of the original physical release, again, exactly as listed.

Season/series pages
As confirmed in a forum discussion, cast lists on season and series pages can have a maximum two subsections. These subsections can only be called recurring and guest. For example, note this abbreviated code taken from Series 6 (Doctor Who):

Cast

 * The Doctor - Matt Smith
 * Amy Pond - Karen Gillan, Caitlin Blackwood
 * Rory Williams - Arthur Darvill, Ezekiel Wigglesworth

Recurring

 * River Song - Alex Kingston
 * Madame Kovarian - Frances Barber
 * Silents - Marnix Van Den Broeke

Guest

 * Abigail Pettigrew - Katherine Jenkins
 * Canton Everett Delaware III - Mark Sheppard, William Morgan Sheppard
 * Idris - Suranne Jones
 * House - Michael Sheen
 * Characters who appear in the majority of episodes, or whose actors' names appear before the titles, shall be listed in the main section labelled cast -- above any subsections.
 * Characters that appear in more than one episode are "recurring", unless all episodes are part of the same story. This includes characters that may have appeared in more than one story across different seasons/stories, so long as the stories are not more than five years apart. For instance, Cassandra O'Brien.Δ17, who appeared in one story in each of series 1 and 2 of Doctor Who, is considered a "recurring" character. William Shakespeare, who was briefly in The Chase in 1965 and more substantively in The Shakespeare Code in 2007, is not a recurring character. Likewise, Jo Jones is not a recurring character for the purposes of the page Series 4 (SJA).
 * Characters that appear in only one story are "guest".
