As I note at the beginning of my essay, “in the early 1960s, director Roger Corman was on fire. Coming off a wave of ultra-exploitational titles for the fledgling film production/distribution company American International Pictures (AIP), which arguably defined late 1950s teen cinema, with such titles to his credit as Premature Burial, Pit and the Pendulum, Creature from the Haunted Sea (all 1961), Last Woman on Earth, The Little Shop of Horrors, House of Usher (all 1960), The Wasp Woman and A Bucket of Blood (both 1959), as well as She Gods of Shark Reef, Teenage Cave Man, Machine-Gun Kelly, War of the Satellites, I Mobster (all 1958), and Sorority Girl, Teenage Doll, Rock All Night, The Undead, Attack of the Crab Monsters and Not of This Earth (all 1957), Corman had mastered genre filmmaking, and was looking around for a new challenge.
The range of Corman’s work during this period is astounding; Pit and the Pendulum and House of Usher were the first two Gothic horror films in Corman’s long-running and highly influential series based on the works of Edgar Allan Poe; A Bucket of Blood and The Little Shop of Horrors were two of the first truly ’sick’ comedies, both shot in a matter of days; Machine-Gun Kelly introduced a young Charles Bronson to audiences, in a period piece designed as a nod to the Warner Bros. gangster films of the 1930s; Teenage Doll and Sorority Girl were pure teen exploitation; and Attack of the Crab Monsters, War of the Satellites and Not of This Earth were clear-cut science fiction.
Most of Corman’s films during this formative period were shot in a week, on budgets of $100,000 or less – The Little Shop of Horrors was famously shot in two days and a night, for roughly $40,000 – although the Poe films represented a real step up for the young director, at least in terms of physical production values. With 15-day schedules, budgets in the $300,000 to $400,000 range, Panavision and Pathécolor, Corman could relax a little, and take some more time with the material.
But even on these films, he often finished ahead of schedule, and he seemed driven to make one film after another, all of them incorporating thematic concerns outside the realm of conventional genre cinema; teen crime, peer pressure, consumerist materialism, even humanist parables, as in Teenage Cave Man, in which the ‘Stone Age’ the protagonists are living in is revealed in the film’s final moments as actually being a post-apocalyptic world after the Third World War has destroyed most of the planet.
While Corman could dabble in social commentary in these films in a rather light and tangential fashion, as a lifelong liberal filmmaker he longed to do something utterly uncompromising. Bolstered by the continuing commercial success of all of his previous films, he decided to direct a film on the racial tensions of the 1960s, shot on location in the American South. And so, right in the middle of his run of commercially successful films for AIP, Corman went off on his own and, with his own money and no studio support, made The Intruder (1962) for a mere $80,000, creating one of the most brutal, honest, and unflinching examinations of American racism in cinema history.”
