Solitude, it’s that is a docu-fiction focusing on the writer Pier Vittorio Tondelli, dead on 16 December 1991, at the age of 36, due to AIDS. Tondelli is known not only for being one of Europe’s greatest storytellers, but also for being one of the sharpest voices of his time. He was the writer of Other Libertines, his first work and a cult novel among young people of the 80s, subjected to seizure in L’Aquila for obscenity and outrage against the public morals of the time. Yet, Tondelli’s novel was not only a transgressive writing, but also a literary project that allowed the linguistic mixing of registers, sectors and even dialectisms. The intellectual from Emilia, however, not only talked about the kids of his time, but also encouraged young writers with the Under 25 project with the aim of giving space in a monthly magazine to budding writers. The film sets out in search of the places where the writer had the opportunity to live, starting from Correggio, where he was born, up to Bologna, the aforementioned L’Aquila and then Orvieto, on which his second novel focuses, to continue with Rome, Milan and Berlin.
