Two small objects were stacked on a worktable in the East Hollywood office of filmmaker Fede Alvarez on a recent morning, one prop each from his first two features. From his feature debut, 2013's "Evil Dead," was a midsized book, crafted and distressed to look like the mystical ancient tome known as the "Necronomicon." From his new film "Don't Breathe" was a simple kitchen baster, its innocent small bulb and pointed end belying the more sinister use it is put to in the film.
