Talk:List of Harry Potter cast members/After 1

 Key The following is a list of cast members who voiced or portrayed characters appearing in the Harry Potter film series. The list is sorted by film and character, as some characters may have been portrayed by multiple actors.
 * (v) indicates the actor lent only their voice for their film character.
 * (y) indicates the actor portrayed the role in a flashback scene or when the character was young.
 * (f) indicates the actor did not appear in any new footage for the film; footage from an earlier film or films was used.
 * A grey cell (such as the one in the "Armando Dippet" row in the "Philosopher's Stone" column) indicates the character was not in the film adaptation.

This is an old version of the current list. It shows the list as it would have appeared after one film. There are other subpages for what the list would have appeared like after two, three, four, five and six films.
