Example Input: Question: Who starred in the film considered to be one of the earliest slasher films? Passage:His work has proved very influential. Bava directed what is now regarded as the earliest of the Italian giallo films, The Girl Who Knew Too Much (1963) and Blood and Black Lace (1964). His 1965 sci-fi/ horror film Planet of the Vampires was a thematic precursor to Alien (1979). Although comic books had served as the basis for countless serials and children's films in Hollywood, Bava's  (1968) brought an adult perspective to the genre with its' Pop art influence of Andy Warhol and Roy Lichenstein. Many elements of his 1966 film Kill, Baby... Kill!, regarded by Martin Scorsese as Bava's masterpiece, also appear in the Asian strain of terror film known as J-horror. 1971's A Bay of Blood is considered one of the earliest slasher films, and was explicitly imitated in Friday the 13th Part 2.
