Sybil (1976)

Wow, this was a fascinating movie. I'm fascinated by multiple personality disorder anyway, and this story just completely engrossed me. Sally Field was absolutely amazing in this role, embodying each one of the personalities in a completely convincing way. I was just blown away by her performance. Although this movie is really long, it didn't feel too long at all. It wound up just exactly when I wanted it to. This movie is really, really interesting - definitely worth watching. 4.5 stars.
