Barney's Version, the movie based on Mordecai Richler's acclaimed novel, is among the high-profile titles making their world debuts at this year's Venice Film Festival.

Organizers of the venerable Italian festival unveiled the lineup for the 67th edition Thursday, with director Marco Mueller touting this year's coup of 79 world premieres.

Canadian-Italian co-production Barney's Version — directed by Richard Lewis, produced by Robert Lantos and starring Paul Giamatti — is among the 22 films that will compete for the festival's highest honour, the coveted Golden Lion.

The film then makes its North American premiere at the Toronto International Film Festival.

Following Tuesday's TIFF announcement in Toronto, Lantos told CBC News that because the Canadian festival’s opening night takes place on Rosh Hashana, the Jewish New Year, he chose not to premiere the film on that date.

Although Richler is undoubtedly a CanLit icon, Lantos has often acknowledged how much Barney's Version is revered in Italy as well.

"The book is so celebrated in Italy and has so many champions that it has become an integral part of Italian popular culture," Lantos said while filming in Rome last fall.
