Adam Williams is frighteningly effective as the "psycho next door" in Without Warning. Normally a quiet, unobtrusive fellow, Carl Martin (Williams) is pushed over the edge when his blonde wife cheats on him. Thereafter, he uses a pair of garden shears to kill every blonde female with whom he comes in contact. The then-new Los Angeles Freeway provides a thrilling backdrop for the film's pulse-pounding final scenes. Without Warning was produced by Arthur Gardner and Jules Levy and directed by Arnold Laven, the same production team that was responsible for such 1950s and 1960s TV weeklies as The Rifleman, Burke's Law and The Big Valley.
