Matthew Betz and May McAvoy in The Terror (1928, dir. Roy Del Ruth), the first sound horror film.
“Black, shrouded death hovers over the picture while the audience shudders and shivers! Flickering lights, ghostly shadows, strange murders, knives flashing in dark places, shrieks & screams, guns blazing out of the darkness, dead bodies falling, appalling situations, a treasure hunt sheeted with deadly angers - and throughout, spine chilling touches of human comedy.”
