Josh Hartnett Starring in Gunslinger Movie
Variety reports that Hartnett will play a gun-fighter in a post-apocalyptic world...a plot that is strikingly similar to Stephen King's The Gunslinger from his Dark Tower series.
A recent report has Josh Hartnett signed on to star in Gunslinger, a revenge story about a man (Hartnett) and his brother who seek retribution against the gang that killed their parents in a post-apocalyptic America. Chris Nahon (Blood: THe Last Vampire) is directing.
If the title and plot sound familiar to you, perhaps you're thinking of author Stephen King's novel The Gunslinger, which is part of his incredibly popular Dark Tower series, or the comic book of the same name, published by Marvel Comics. King's plot concerns a gunslinger's quest to catch "the man in black" in a post-apocalyptic or alternate time-line world.

I'm ok with it, actually. Josh Hartnett isn't a bad actor, he just tends to choose shitty movies. And I think he can pull off sexy rugged grunge.
