Touch of Evil 1958 American film noir written and directed by Orson Welles, who also stars in the film, alongside Charlton Heston, Janet Leigh, Joseph Calleia, Akim Tamiroff & Marlene Dietrich.

Initially dismissed by film critics, Touch of Evil found popularity among European audiences and won top awards at the 1958 Brussels World Film Festival. During the 1970s, its reputation was renewed and it is now widely regarded as one of Welles's best motion pictures and one of the best classic-era noir films as well as one of the last. Touch of Evil was re-edited according to Welles's original vision, as outlined in his memo, in 1998.

In 1993, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
