The SAW opening sequence uses loud sound effects and a twisting logo to set an ominous tone. In darkness, the audience hears a man screaming and struggling in water, building tension. When lights turn on, he sees a dead body, implying the characters are in danger.
The SE7EN opening uses unsettling music and electronic sounds to make the audience feel anxious. The handwritten credits are uneven, fitting for a horror film. Quick cuts between disturbing images of skin picking and other acts heighten the sequence's intensity, drawing viewers into the psychological horror elements without context from the full film.
