Festival organizers said Martin Scorsese would not be coming to present his four-hour tribute to Italian cinema, which is showing out of competition.

Scorsese, who won the festival's top prize in 1976 for "Taxi Driver" and headed the jury in 1998, had been scheduled to appear Wednesday to present "My Voyage in Italy," about the Italian films that have influenced him as a director.

But he canceled his visit so he could finish editing "Gangs of New York," starring Leonardo DiCaprio, Cameron Diaz, Liam Neeson and Daniel Day-Lewis. The period movie centers on the clash between New York's Anglo-Protestant poor and the United States' next big wave of immigrants, the Catholic Irish.

It was filmed in the Cinecitta studio in Rome.
