Movie bosses at Buena Vista have upset Venetian Mayor MASSIMO CACCIARI by axing plans to give the city's film fans a special open-air preview of new movie CASANOVA, which was shot in the Italian city.

Instead, the film's world premiere will be staged at the upcoming Venice Film Festival (02SEP05) - but for special guests only.

Cacciari, who waived many city filming restrictions to help movie-maker Lasse Hallstrom and his cast, including Heath Ledger as the infamous Venetian lothario and Jeremy Irons, has taken the news there will be no public viewing badly.

He says, "Venice participated generously in the shooting of this film. If it won't screen in Campo San Polo (famous city location), we will consider that an insult."

But Buena Vista's Italian boss PAUL ZONDERLAND tells movie industry magazine Daily Variety that the decision not to publicly screen the film was made to protect the project from pirates.

He explains, "We have to protect a multi-million dollar investment from piracy. That is our only issue."

The film isn't released in America until Christmas (05).
