The Woman in White
The lead Florence La Badie plays dual roles. Clever editing is used for the scene where her two characters meet. La Badie, however, does appear twice within a scene via superimposition, but that's in a flashback-within-a-mirror scene. There are a couple such scenes where La Badie's reflection in the mirror reflects her reflective melancholy mood.
