TORONTO - "Up In the Air" director Jason Reitman will mentor new talent at the Toronto International Film Festival.

The Oscar-nominated Reitman and distribution veteran Bingham Ray have been chosen to guide 24 artists in the festival's intensive talent lab. It runs Sept. 7 to 10.

Meanwhile, emerging actors Sarah Allen, Katie Boland, Sarah Gadon and Keon Mohajeri will be the first participants in the festival's Rising Stars program.

TIFF says it's designed to help homegrown talent break internationally. The foursome will get a chance to network with casting directors, agents, managers, producers and filmmakers.

The programs are in addition to a pitch event Sept. 13, when six teams get to pitch their feature film idea to a jury and live audience. The winning team gets $10,000 from Telefilm Canada to put towards their project.

The Toronto International Film Festival runs Sept. 8 to 18.

Gadon's resume already includes roles in David Cronenberg's films "Cosmopolis" and "A Dangerous Method," as well as Mary Harron's "The Moth Diaries." Allen's early credits include supporting roles in "Human Trafficking" and the "Secret Window," with recurring roles in "Little Mosque on the Prairie," "MVP," "Murdoch Mysteries" and "Being Human."

Boland is currently filming Paul Thomas Anderson's "The Master" with Phillip Seymour Hoffman and next year makes her literary debut with the short story collection, "Eat Your Heart Out." Mohajeri's film and television appearances include "Flashpoint," "Good Dog," "Bloodletting and Miraculous Cures," and "Murdoch Mysteries."
