Honestly, that's far more churlish than Telluride's co-directing triumvirate Tom Luddy, Gary Meyer and Julie Huntsinger would ever be in addressing the fact that earlier this year, the utterly vital and massive Toronto International Film Festival (Sept. 4-14) laid down the law.
"I'm deeply touched that the board of the Telluride Film Festival decided to honor Roger this way and I send my sincere thanks and congratulations on their 40-year anniversary to festival directors Tom Luddy, Gary Meyer, and Julie Huntsinger," Eberts wife, Chaz, said in a statement.
"The festival's founders [Bill and Stella Pence] are in their 70s, and we wanted to celebrate this incredible thing they built and we're carrying on, in a really big way," says executive director Julie Huntsinger, whose fellow fellow directors are Gary Meyer and Tom Luddy(also a festival cofounder
