[4] After early work as a lifeguard, competitive chess player, surfing instructor and waiter,[5] Longo began to write for the stage, radio and film.
He co-wrote the script for Lina Wertmüller's film Io speriamo che me la cave, with whom he published in 1992 a volume containing two stories: Prima o poi tornerò was his contribution, while Alì Babà was written by the director.
[3] In 2007, Longo published Dieci, a collection of short stories set in Naples with themes based on the Ten Commandments.
He adapted his work Più o meno alle tre, which was directed by Emanuela Giordano and staged by the Roman group Cometa Off in 2003.
His earlier works Chi ha ucciso Sarah (1998) and Un pensiero per Olga (1999) can be cited, as well as Falene which debuted in Naples in 2004 under the direction of Marcello Cotugno.
