The filmmaker shot his latest project in Rome, Italy with Penelope Cruz, Alec Baldwin and Jesse Eisenberg, and the original title was slated to be The Bob Decameron.
But Allen has decided to change the name to Nero Fiddled because the former title drew blank expressions.
He says, "I couldn't believe how few people had heard of The Decameron, even in Rome. And the few that did assumed the movie was based on Boccaccio's tales, which it's not.
"Anyhow changed the title to Nero Fiddled, which is the first time I've changed a title since my last minute switch of Anhedonia to Annie Hall."
The Decameron is a frame story consisting of 100 tales by Giovanni Boccaccio, depicting aspects of life in 14th Century Italy.
