Unlike later Halloween specials, there are no "funny" names for the cast members - everyone is just credited normally.
Although the actual, official title of the episode is "Treehouse of Horror", the opening screen gives the title as "The Simpsons Halloween Special" This is true of this and all subsequent Halloween episodes.
Edgar Allan Poe is listed in the opening credits as a writer as the episode refers to and quotes from his classic poem "The Raven".
This episode dispenses with the usual opening credits and cuts straight into the action.
