In theaters now: The Danish Girl, directed by Oscar winner Tom Hooper.

The movie is adapted from David Ebershoff's novel of the same name, which fleshes out the incredible-but-partly-true romance of Lili Elbe and Gerda Wegener as Lili transitions from male to female in the early part of the last century.
