Directed by Ingmar Bergman
Persona is one of my favorite films of all time. It has several great scenes in it. This is one of the less obvious choices (those who have seen the film will know the more obvious choice). I think this scene is one of the most erotic scenes in cinema history. Even more erotic than most on-screen sex scenes out there. This film about an actress (Liv Ullmann) who was rendered inexplicably mute is sent to the seaside with a psychiatric nurse (Bibi Andersson) as part of her therapy. And it just gets weird from there. Bibi Andersson basically speaks roughly 90% of all the spoken dialogue in the entire film so she has a lot of long monologues and this is one of them.
