In the fading atmosphere of the New Hollywood era, William Friedkin – the wunderkind director with an Academy Award for his cop drama, The French Connection (1971) who then scored an even bigger success with The Exorcist (1973) – began work on what would prove to be the most controversial film of his career: Cruising (1980). In the process he established a template for a sub-genre, the serial killer thriller, that would thrive long after his film had left theatres, having caused widespread offence among the very audience he'd hoped to appeal to, via a campaign mobilised by the counter-culture press. As such, Cruising can be read as a bitter farewell to the seventies and its cinema and industry. This Devil's Advocate dives deep into the phenomenon that is Cruising , examining its creative context and its protagonists, as well as examining its ongoing popularity as it turns 40 in 2020.
