It is 1930 in Denmark. A painter and his wife, who is also a painter, explore his sexual ambiguity. She is a willing partner in his gender dysphoria. He finds a thrill in dressing up as a girl, and men find her attractive. The wife finds fame painting her husband as a woman.
Interesting premise.
Transgenderism is weird. Gender is so central, so basic to who someone is -- such a gestalt of so many clues -- that dressing up as the other gender rarely is convincing, even in real life. Yet here, the director (and actor) really made it work.
Based in part on a true story, the painter, Einar Wegener, ends up having one of the first gender reassignment surgeries in history. Sadly, the story does not end well.
