The decade also saw the emergence of the youth subculture best represented by the Beatles and rock and roll. As a result, certain movie genres were made to cater to this trend. Fan movies and teen love team-ups emerged, showing Nora Aunor and Vilma Santos, along with Tirso Cruz III and Edgar Mortiz as their respective screen sweethearts. In addition, movie genres showing disaffection to the status quo during the era were also popular. Action movies with Pinoy cowboys and secret agents as the movers of the plots depicted a "society ravaged by criminality and corruption". Another kind of youth revolt, implying rejection of adult corruption, came in the form of movies featuring child stars. Near the end of this decade, another movie genre that embodied a different form of revolt took center stage. Soft porn movies, more popularly known as "bomba" films, increasingly became popular, and these films were described as a direct challenge to the conventions, norms and conduct of the society.
