Bei Anruf Mord
Jack L. Warner, the co-founder of the Warner Brothers film studio, had briefly assigned Fehr to production duties in 1952. Fehr then edited two films directed by Alfred Hitchcock, "I Confess" (1953) and "Dial M for Murder" (1954). Following "Dial M for Murder" (1954), Warner appointed Fehr as the Head of Post-production including the editing department. Hitchcock made his next films for Paramount Pictures, where George Tomasini became Hitchcock's principal editor in an important collaboration.
