I bring this up because that very story is about to be brought to the big screen by Ira Sachs, who also wrote the screenplay (he did the same double-duty on last year's inexplicably praised Forty Shades of Blue). Here's the one big difference (apart from the fact that my fantasy star is long-dead): Sachs' film, entitled Marriage, is a drama. Wha? So, he's going to make a serious movie about a guy sincerely trying to spare his wife by killing her? That sounds ... interesting. I guess. Maybe they're setting it in the 1940s so that the period atmosphere will make his actions seem rational, or something.
In talks to star in the film are Pierce Brosnan, Chris Cooper, Rachel McAdams (She better be a freaking daughter, and not the girlfriend -- is she even half Brosnan's age?), and Patricia Clarkson; Sachs hopes to begin shooting in a few months.
