Lars von Trier has said that "a film should be like a stone in your shoe".
I have not seen any of his other films, but this one certainly fit that bill. It is definitely a movie I will be thinking about for some time. You can read plot summaries by JSP and Cat, and I'm kind of glad I don't have to try to explain it. Although the outline of the plot is simple enough. It's the depth of the chaos that goes on when the couple go to the cabin that is...well, batshit crazy. I'm still not entirely sure how I feel about it.
The filming and cinematography is beautiful. Amazing at times. Completely horrifying at times.
The actors, Willem Dafoe and Charlotte Gainsbourg, are incredible. Their discussions and exchanges are so intense - even when being gentle. Truly a tour de force for both of them.
As JSP mentioned - it's hard to figure out what von Trier's message is with this movie. Certainly it's a statement on grief. However it also delves deeply into the mystery of Nature and human nature - and specifically the extreme dark sides of both. Many critics derided the film for its misogynistic themes. In fact, " The ecumenical jury at the Cannes festival gave the film a special "anti-award" and declared the film to be 'the most misogynist movie from the self-proclaimed biggest director in the world'." Interestingly, von Trier's production company is considered the first mainstream film company to produce hardcore pornographic films directed specifically towards female audiences. A quote from Wikipedia, "Women too like to see other people having sex. What they don’t like is the endless close-ups of hammering bodyparts without a story. Lars von Trier is the first to have realised this and produced valuable quality porn films for women." A misogynist who makes quality porn for women is something of an oxymoron in my book. Maybe that's just me.
While there are parts of Antichrist that are definitely pornographic - it is still a horror flick. Granted, it's a character driven horror flick, but I still hid my eyes on a couple of occasions. I'm not quite as in love with it as Freeek or JSP. I think that's mostly because I like a little more clarity in my movies. But I still definitely recommend it.
