You will never see Sallah's face in dwarf facial appliances again. Speaking to Empire, John Rhys-Davies--Gimli of Lord of the Rings--explained that he's already declined appearing in future Tolkien adventures (though, in a parallel Sliders universe, he's probably playing every role in The Hobbit):
While Gimli doesn't appear in The Hobbit, his father Gloin does, so we asked him recently whether he'd be back for another go.
"I've already been asked and to be honest with you, I wouldn't. I have already completely ruled it out. There's a sentimental part of me that would love to be involved again. Really I am not sure my face can take that sort of punishment any more."
His mouth says his face can't take the punishment, but his résumé says he's just too busy making original movies for SyFy and Cinemax.
