Basically, if the year overall has been stuffed to the gills with good movies then Cannes will have a great edition. But if the vintage is not a good one, it will show down on the riviera. On the other hand, Toronto and the Venice Film Festival (the "Mostra") have the perfect time slot. Because anything that's been done in the first half of the year will be scheduled for a Mostra or a Toronto premiere--once the large blockbusters have cleared the Summer pipeline, here come the indie and foreign heavy-hitters; but sales will go in a frenzy at Toronto, since the Mostra does not have a market.
The beautiful Marisa Tomei will be starring opposite George Clooney and Ryan Gosling in "Ides of March," which will premiere at the next Venice Mostra.
