Fan Casting Finli in Ron Howard's Dark Tower: The Gunslinger

A Taheen—a creature with the head of a weasel—and Pimli's partner in overseeing the Breakers. Tall and lean, with a calm pragmatism, Finli is the steady hand next to Pimli's nervous terror. He comforts his partner with soft words, reminding him to breathe, even as they both know they are one failure away from Walter's wrath. He is competent, efficient, and terrified—a weasel waiting for the trap to snap.
