Othello or Nora are definite, substantial figures created by the playwright. They can be played well or badly, and they can be "interpreted" in one way or another; but they most definitely exist, no matter who plays them or even whether they are played at all. The character in a film, however, lives and dies with the actor. It is not the entity "Othello" interpreted by Robeson or the entity "Nora" interpreted by Duse, it is the entity "Great Garbo" incarnate in a figure called Anna Christie or the entity "Robert Montgomery" incarnate in a murderer who, for all we know or care to know, may forever remain anonymous but will never cease to haunt our memories.
