Roland's two handed revolver reloading technique
I'm pretty sad that we're not going to get to see that. The shot they've revealed of the Horn of Eld shows him carrying multiple loaded cylinders for his pistols. I do get it though. It's probably next to impossible to do what King describes in the book. I know I sure as hell couldn't do it, and I know my way around a gun or two.
Though now that I think of it, he stopped being able to do that because of the lobstrosities taking his fingers. You think we'll get to see the lobstrosities in this or the sequels? I always had a hard time visualizing those things. I can't remember how they are described word for word, but I know it was a little more detailed than just gigantic lobsters. I'm pretty sure it was Eddie who coined "lobstrosities" wasn't it?
I thought I could paint it red, but I couldn't find enough goats.
