Yeah, such as it comes to Fistful/Yojimbo, now that you mention it, I guess I can say now that if I do it - I'm actually gonna do a three-piece of Yojimbo, Fistful Of Dollars, and Last Man Standing. The connection is the three basically have the same premise (LMS is even credited, screenplay-wise, to Kurosawa), but the three different filmmakers went about it in very different ways. It's cool seeing how Leone took from Kurosawa (so much so they actually got sued! yikes!) and then how much Walter Hill also ended up taking from Leone.
But yes, I'll probably go for something random, since working up the Yojimbo/Fistful/Last Man thing is gonna be a big undertaking. But thanks for suggesting the idea, I wasn't thinking to do so originally. O_O!
I still wanna do a remake of Fistful as "A Fistful Of Pills", as a small scale Running Scared-esque adrenaline flick about a drug addict turning the two groups of dealers against eachother just to get a stash that he can live off of for the rest of his life. Yeah, I'm weird like that.
