Among the world premieres are "Encounters at the End of the World," in which Herzog ("Grizzly Man") leaves the bears behind to take viewers to Antarctica. Macdonald, whose "The Last King of Scotland" unspooled in Toronto last year, looks at the postwar activities of former Gestapo commander Klaus Barbie (aka "the Butcher of Lyon") in "My Enemy's Enemy"; and former talkshow host Donahue teams with Ellen Spiro to take a hard look at the toll of the Iraq War in "Body of War."

Also on the Real to Reel slate: Scott Hicks ("Shine") turns the camera on Glass, documenting a year in the life of the composer as he interacts with the likes of Chuck Close, Ravi Shankar and Woody Allen in "Glass: A Portrait of Philip in Twelve Parts," while Peter Askin's "Trumbo" tells the story of the blacklisted screenwriter through spoken-word performances of his extraordinary letters by Donald Sutherland, Michael Douglas, Joan Allen and Liam Neeson.

Political docs on offer in Toronto include Ted Braun's "Darfur Now"; "The Dictator Hunter," from Klaartje Quirijns; Siatta Scott Johnson and Daniel Junge's "Iron Ladies of Liberia"; and Nina Davenport's "Operation Filmmaker."

Also featured: "A Jihad for Love," "Obscene," "Very Young Girls" and "Surfwise."

Fest programmers have added a number of titles to the Vanguard program, including Gus Van Sant's Cannes offering "Paranoid Park" and Mexican thesp Gael Garcia Bernal's directorial debut "Deficit," in which he also stars.

The long-awaited conclusion of Dario Argento's the Three Mothers trilogy, "The Mother of Tears," has been added to the Midnight Madness slate, as has "Sukiyaki Western Django," cult cinema bad boy Takashi Miike's first English-language film.

Fest runs Sept. 6-15.
