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".
Mariangela Melato (19 September 1941 – 11 January 2013) was an Italian cinema and theater actress.
 She began her stage career in the 1960s.
 Her first film role was in "Thomas e gli indemoniati" (1969), directed by Pupi Avati.
 She played in many memorable films during the 1970s, a period which was considered her golden age, and she received much praise for her roles in films like "Between Miracles" (1971), "The Seduction of Mimi" (1972), "Love and Anarchy" (1973), "Nada" (1974), "Swept Away by an Unusual Destiny in the Blue Sea of August" (1974), "Todo modo" (1976) and "Il gatto" (1978).

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).

Giuseppe Avati, better known as Pupi Avati (born 3 November 1938), is an Italian film director, producer, and screenwriter.
 He is known to horror film fans for his two masterpieces of the macabre, "The House with Laughing Windows" (1976) and "Zeder" (1983).
The Hideout (Italian: Il nascondiglio ) is a 2007 Italian-American mystery film written and directed by Pupi Avati.

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.
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."
L'arcano incantatore, internationally released as The Mysterious Enchanter, is a 1996 Italian horror film directed by Pupi Avati and set in the 18th century.
