Filmmaking style and themes
Franco sometimes worked under various pseudonyms, including David Khune and Frank Hollmann. A fan of jazz music (and a musician himself), many of his pseudonyms were taken from jazz musicians such as Clifford Brown and James P. Johnson.
Franco's themes often revolved around lesbian vampires, women in prison, surgical horror, sadomasochism, zombies and sexploitation (including numerous films based on the writings of the Marquis de Sade). He worked in other exploitation film genres, such as cannibal films, spy films, giallo, crime films, science fiction, jungle adventure, Oriental menace, exorcist films, war movies, historical dramas and nunsploitation. His sex movies often contained long, uninterrupted shots of nude women writhing around on beds. Most of his hardcore films starred his lifelong companion Lina Romay (sometimes billed as "Candy Coster" or "Lulu Laverne"), who admitted in interviews to being an exhibitionist.
Franco was known for his use of a hand-held camera and zoom shots, which he felt lent realism to his films. He also was not averse to filming several movies at the same time, knocking together a second feature on the unsuspecting producer's dime. Many of his actors only found out years after the fact that Franco had actually starred them in films for which they had never even been paid.
His main claim to fame, however, is that he managed to direct approximately 173 motion pictures in his lifetime, encompassing a wide swathe of different genres with practically no financial backing available to him. (Note: Some sources which list as many as 200 titles in Franco's filmography are relisting the same films several times under their different variant titles.)
Sometimes referred to as the "European Ed Wood", Franco similarly attracted a circle of bizarre but loyal actors and technicians who moved with him over the years from project to project (while receiving very little, if any, money for their efforts). Many of his actors were over-the-hill performers in the twilight of their careers, many of his actresses brazen exhibitionists. He frequently worked with genre actors Lina Romay (who appeared in 109 Franco films), Antonio Mayans (who appeared in 50 Franco films), Howard Vernon (who appeared in 40 Franco films), Paul Müller (who appeared in 15 Franco films), Monica Swinn (who appeared in 15 Franco films), and Christopher Lee (who appeared in 7 Franco films). His frequent cast members also included Jack Taylor, Ewa Strömberg, Anne Libert, Soledad Miranda, Maria Rohm, William Berger, Dennis Price, Olivier Mathot, Muriel Montosse (a.k.a. Victoria Adams), Alice Arno, Montserrat Prous, Alberto Dalbés, Britt Nichols, Pamela Stanford, Mabel Escaño, Kali Hansa, Carmen Carrión and Klaus Kinski, all of whom are well known to Euro horror film historians.
