to the public, and Eva visiting Diabolik's gold-encased body in the Hall of Ministry rather than in their hideout. Lucas believes that many of Bava's alterations to the screenplay served to make the characters more sympathetic and believable, and notes that many of the film's wittiest and most memorable moments, such as Diabolik and Eva's lovemaking on top of the stolen $10 million (a parody of Horst Buchholz covering Catherine Spaak's nude body with lira notes in The Empty Canvas) and Valmont's threat to "cross [Dr. Vernier] from the human register", were entirely the director's creation. Bava was permitted by De Laurentiis to utilize many of the key crew members of several of his most recent films (namely Planet of the Vampires and Kill, Baby, Kill), such as his son and assistant director Lamberto Bava, editor Romana Fortini, cinematographer Antonio Rinaldi, and script supervisor Rosalba Scavia. The film's art direction was led by Flavio Mogherini and two-time Oscar winner Piero Gherardi: Mogherini, who had last worked with Bava on The Wonders of Aladdin, was also responsible for the film's scale model effects, while Gherardi, who had designed sets for films that Bava had shot early in both men's careers, also assisted Luciana Marinucci with the film's costume designs. Other crew members would also become future Oscar winners: Carlo Rambaldi, who had previously provided special effects for Planet of the Vampires and created Diabolik's form-fitting mask, would be recognized for his work on E.T. the Extra-Terrestrial, as would composer Ennio Morricone for The Hateful Eight. Casting John Phillip Law was invited to audition for Diabolik as a favor by De Laurentiis after production on Barbarella, which Law had been cast in as Pygar, was delayed due to technical difficulties, allowing director Roger Vadim and his wife and star, Jane Fonda, to make the "Metzengerstein" segment of Spirits of the Dead. An avid comic book fan since childhood, Law was initially unfamiliar with the characters in Diabolik, and read several of the comics to understand his character, as he had done when preparing for Barbarella. Due to most of the character's face being hidden by a black or white skin-tight mask, Law noted that the most prominent aspect of Diabolik's appearance was his eyebrows; he prepared for the role by applying mascara to his own, and taught himself to convey a wide array of expressions with them.
