TORONTO - Guitar gurus Jimmy Page and Jack White, fashion icon Valentino and a massive Chinese restaurant will be among the documentary topics explored at this year's Toronto International Film Festival.

In "It Might Get Loud," David Guggenheim - the Oscar-winning director of "An Inconvenient Truth" - looks at the electric guitar by studying the creative process of Page of Led Zeppelin, White of the White Stripes and The Edge of U2.

"Valentino: The Last Emperor" is a look at the designer and his entourage by Vanity Fair correspondent Matt Tyrnauer.

And "The Biggest Chinese Restaurant in the World," by Weijun Chen, examines the West Lake Restaurant in Changsha, China, said to be the world's largest restaurant.

Other documentaries include "A Time to Stir" - a four-hour work-in-progress by American Paul Cronin about the 1968 student strike at Columbia University; "Youssou Ndour: I Bring What I Love," a look at African tenor Youssou Ndour; and "American Swing," chronicling the rise and fall of a New York sex club.

The festival previously announced that Larry Charles - whose last project, "Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan"- was a smash at the festival two years ago, will be back with " Religulous." It follows humorist Bill Maher as he interviews people about God and religion.

The festival runs from Sept. 4 to 13.
