Question: Scott Derrickson and Umberto Lenzi, have which mutual occupation?
Context: Brothers Till We Die (Italian: La banda del gobbo ) is a 1977 Italian poliziottesco-action film by Umberto Lenzi.  This film is the last collaboration among Lenzi and Tomas Milian.  In this movie Milian plays two characters, Vincenzo Marazzi a.k.a. "The Hunchback" that he already played for Lenzi in "Rome Armed to the Teeth", and his twin brother Sergio Marazzi a.k.a. "Er Monnezza", a role that he played for the first time in Lenzi's "Free Hand for a Tough Cop" and later resumed in "Destruction Force" by Stelvio Massi. The Cynic, the Rat and the Fist (Italian: "Il cinico, l'infame, il violento" , lit.  "The Cynic, the Infamous, the Violent") is an Italian poliziotteschi crime action thriller directed in 1977 by Umberto Lenzi.  The movie is the sequel to Lenzi's 1976 "The Tough Ones", with Maurizio Merli reprising the role of Commissioner Leonardo Tanzi. Free Hand for a Tough Cop (Italian: Il trucido e lo sbirro / The Numbskull and the Cop ), also known as "Tough Cop", is an Italian poliziottesco-action film directed in 1976 by Umberto Lenzi.  In this movie Tomas Milian plays for the first time Sergio Marazzi a.k.a. "Er Monnezza", a role that he later played several more times, in Lenzi's "Brothers Till We Die" (1978, a sort of sequel of this movie), in "Destruction Force" by Stelvio Massi (1977) and, with slight differences, in "Uno contro l'altro, praticamente amici" by Bruno Corbucci (1980) and in Francesco Massaro's "Il lupo e l'agnello" (1980). Seven Blood-Stained Orchids (Italian: Sette orchidee macchiate di rosso ) is a 1972 Italian giallo film directed by Umberto Lenzi, who also co-wrote the screenplay.  Lenzi said in interviews that this film was his favorite giallo, next to "Orgasmo" (1969).  This film was also released in Germany as Puzzle of the Silver Half-Moons, and in France as Farewell, Killer.  The script of the film is loosely based on two novels (one by Edgar Wallace and one by Cornell Woolrich), and it was the last film based on Wallace's works until a series of TV-movies produced in Germany in the mid-1990s.  The German version of the film had a different opening credits sequence that emphasized its Edgar Wallace origins.  The film's Riz Ortolani theme song "Why?"  was recycled from the soundtrack of Lenzi's earlier film, "So Sweet... So Perverse". Il coltello di ghiaccio is a 1972 Italian giallo film directed by Umberto Lenzi and starring Carroll Baker, Evelyn Stewart and George Rigaud.  Both Baker and Stewart featured in several other films helmed by Lenzi.  The film follows a mute woman who finds herself in danger when a serial killer begins stalking the Spanish countryside.  The title takes its name from a quote by Edgar Allan Poe, in which he refers to fear as a "knife of ice which penetrates the senses down to the depth of conscience." Scott Derrickson (born July 16, 1966) is an American director, screenwriter and producer.  He lives in Los Angeles, California.  He is best known for directing horror films such as "Sinister", "The Exorcism of Emily Rose", and "Deliver Us From Evil", as well as the 2016 Marvel Cinematic Universe installment, "Doctor Strange." Umberto Lenzi (born 6 August 1931) is an Italian film director who was very active in Italian international co-production peplums, Eurospy films, spaghetti westerns, Macaroni Combat movies, Poliziotteschi films, cannibal films and giallo murder mysteries (in addition to writing many of the screenplays himself). Super Seven Calling Cairo (Italian: Superseven chiama Cairo) is a 1965 Italian Eurospy film directed by Umberto Lenzi and filmed in Egypt.  It is directly inspired by James Bond.  It was based on a novel written by Umberto Lenzi.  It starred Roger Browne and Massimo Serato, and a young Rosalba Neri. From Hell to Victory is a European Macaroni-War film directed in 1979 by Umberto Lenzi.  The movie was a co-production between Italy (where it was released as Contro 4 bandiere/ "Against Four Flags"), France (where is known with the title De l'enfer à la victoire) and Spain (where is known as De Dunkerke a la victoria/ "From Dunkirk to Victory").  Some internationally distributed versions credit Umberto Lenzi as "Hank Milestone". Black Demons (released on video as Demoni 3) is a 1991 Italian horror film directed by Umberto Lenzi (his last horror film).  It was written by Lenzi and his wife Olga Pehar, and the zombie makeup fx were handled by Franco Casagni.  Lenzi said in later interviews that this was one of his favorite films, but he felt it was ruined by the low budget and some of the shoddy actors he was forced to work with.  Lenzi intended the film to be called "Black Demons", and he did not like it when the film was later retitled "Demoni 3" on video, because some people thought it was part of Lamberto Bava's "Demons" series, which it had absolutely nothing to do with.
