Well, it depends on who you ask. The Toronto Star did just this. They talked to various prominent festival goers and compiled their answers here: TheStar.com | Film Fest | TIFF’s must-see films.
Some of these will be no surprise (e.g., the new film from the Coen brothers). But others will be. Here’s a chance to start planning what to see either at the festival or in the upcoming months as these films come out for general release.
BTW, the Star has alot of good information on the Festival. Be sure to poke around their site.
