Time for categories for book authors with enough gun-using film adaptations?

[Evil Tim]

I can't really see much call for this, to be honest; when you look at a page you might want to look up another film by the same director, but I can't really see anyone thinking 'hey, I wonder what guns were in other movies based on short stories by the same author.' Being a franchise, Clancy is more like a producer than a writer, and King isn't just a writer, he's also acted and even directed (though people try to forget about Maximum Overdrive as a rule).
