It's a difficult undertaking. I've been married for four years and I see this movie as a cautionary tale about people who've gone deeply out of communication.
I don't like this idea of Method. I come from that school, but what I was taught was that it's your imagination. You do your homework, and you use your imagination.
I think of marriage as a garden. You have to tend to it. Respect it, take care of it, feed it. Make sure everyone is getting the right amount of, um, sunlight.
I like to think the movies that I've picked have something worthwhile to say. Something relevant.
