A number of days ago, I had a dream where I watched a movie with red-and-cyan colour grading (You know, like the early Technicolor movies from the '20s.)
about a man who killed his wife with a purple plastic pie cutter
[It's not purple, but you get the picture.]
after she found out he was having an affair with her identical twin sister. The twins -- played by the Canadian actress Lauren Lee Smith
-- had pretty much the exact same haircuts Julie Christie sported in the film adaptation of Fahrenheit 451.
Oh, and after the husband did the deed, he did a shitty job of covering up his tracks, leaving fingerprints everywhere.
Damn, now that I think about it, I wish that was a real movie, blatant similarities with Rear Window notwithstanding.
