I've never been a big fan of the western genre except for the Clint Eastwoods and a handful of spaghetti westerns like the Django and Sabato series. Recently, I've come across several really great westerns that are dark, gritty, and oh-so-noir-ish.
Mannaja: A Man Called Blade directed by Sergio Martino (Horror Express),
Winchester '73 directed by Anthony Mann (Raw Deal), and
McCabe & Mrs. Miller directed by Robert Altman (M*A*S*H).
In particular, the latter is an excellent and realistic depiction of frontier life in the 1880s. A gambler (Warren Beatty) opens up a whorehouse in a mining town and brings in a seasoned madam to run it (Julie Christie). When their operation
becomes too successful, it attracts the attention of the mining company who offers to buy them out... or else! Reminds me of a David Goodis novel as the protagonist, McCabe, is weak and flawed but likable. You
want him to win, to overcome his inner demons and become a hero even though the odds are very much against him... I won't spoil anything by giving away the ending. It also reminds me a bit of the protagonist, Jimmy, in my zombie novel,
Deathbreed.
Even though I love horror movies, the older I get, the more I find I like to explore different genres. I've already seen just about every horror movie (foreign and domestic) that I care to see and I don't see too many worthy new
ones being released. I can't just watch the same stuff over and over. The lack of quality new releases forced me to check out all kinds of other stuff over the past decade... and I've been pleasantly surprised! I think exposing myself to so many different genres and influences has been invaluable in making me a better writer and filmmaker.
Anyway if you're looking for something dark but not full of zombies, vampires, or axe-wielding maniacs, do yourself a favor and see what else the world has to offer. Chances are you'll be glad you did!
