In the late 1960s and early 1970s, a new generation of low-budget film companies emerged that drew from all the different lines of exploitation as well as the sci-fi and teen themes that had been a mainstay since the 1950s. Operations such as Roger Corman's New World Pictures, Cannon Films, and New Line Cinema brought exploitation films to mainstream theaters around the country. The major studios' top product was continuing to inflate in running time—in 1970, the ten biggest earners averaged 140.1 minutes. The Bs were keeping pace. In 1955, Corman had a producorial hand in five movies averaging 74.8 minutes. He played a similar part in five films originally released in 1970, two for AIP and three for his own New World: the average length was 89.8 minutes. These films could turn a tidy profit. The first New World release, the biker movie "Angels Die Hard", cost $117,000 to produce and took in more than at the box office.
