I read about Tony Manero for the first time one or two years ago (it was on Dell on Movies, if I'm not wrong), and I found the concept very interesting. So my quest for the past years has been to find the movie and watch it.
Set in Santiago, Chile, during the dictatorship of Pinochet in 1970s, the film follows Raúl (Alfredo Castro), a 52-year-old unemployed man who is obsessed with Tony Manero, John Travolta's character in Saturday Night Fever, so obsessed that he watches the movie in the local movie theatre on repeat in order to memorize the dialogue and especially all of Travolta's dance moves. This guy wants to be Tony Manero so bad, he's willing to do anything to achieve his goal.
