With summer on its last legs, it's time to turn our attention to the two big fall movie festivals, and sort out the Oscar contenders that will vie for cinematic immortality next spring. That, and there's some really great films coming to theaters.

While the Venice Film Festival will unveil their lineup later this week, the Toronto Film Festival has pulled the curtain to reveal their lineup, and it features a collection of critically-buzzed about movies.
 
Kicking things off on opening night will be the world premiere of Academy Award-winning documentarian Davis Guggenheim's From the Sky Down, a film chronicling the creation of rock band U2's best-selling album Achtung Baby. Guggenheim previously helmed An Inconvenient Truth (for which he won the Best Documentary Oscar) and last year's Waiting for Superman.
 
Brad Pitt and Jonah Hill in Moneyball.If documentaries aren't your thing, TIFF has plenty of narrative films to lure you to a screening. Among those vying for attention: baseball drama Moneyball starring Brad Pitt and Jonah Hill; A Dangerous Method starring Keira Knightley, Viggo Mortensen and Michael Fassbender; 50/50 with Seth Rogen and Joseph Gordon-Levitt; and Gerard Butler in Machine Gun Preacher.
 
Two movies starring George Clooney will also premiere at the festival. In The Ides of March, Clooney stars as a Democratic presidential candidate who schools his idealistic campaign press secretary (played by Ryan Gosling) on some questionable practices of modern politics. Clooney also directs the edgy political drama.
 
On the other end of the spectrum, Clooney stars in Alexander Payne's comedy The Descendants. In the film, Clooney plays the patriarch of a Hawaiian family who learns a secret from his critically ill wife, and must decide what to do with the family's last parcel of land. A trailer debuted a couple months ago, which you can watch here.
 
Ryan Gosling in Ides of March.Other major American films making their debut include Roland Emmerich's Shakespearean thriller Anonymous; Friends with Kids starring Megan Fox, Jon Hamm, Kristen Wiig and Ed Burns; Jeff Who Lives at Home starring Jason Segel and Ed Helms; Channing Tatum's Ten Year; Woody Harrleson and Steve Buscemi's Rampart; Chole Moretz and Blake Lively's dramedy Hick; and Francis Ford Coppola's gothic horror Twixt starring Val Kilmer and Elle Fanning.
 
The festival will also include an array of critically-loved festival favorites from throughout the year including Drive, Melancholia, Take Shelter, Martha Marcy May Marlene, The Skin I Live In, Like Crazy, Tyrannosaur and many more.
