Don’t waste your time watching studio schlock this Halloween. Instead, see some eerie classics at Speed Cinema. On Friday and Saturday, there will be screenings of the unsettling “Eraserhead,” by the David Lynch. Also on Saturday, catch “Carnival of Souls,” a B movie about a woman “compelled by a foreboding, ghostly figure to visit an abandoned lakeside carnival grounds.” And on Sunday, see a “frothy mix of gore, terror, and beauty [that] leaves an indelible mark on the psyche,” in “Eyes Without a Face.”
