TORONTO - The Toronto International Film Festival has ramped up its star power with titles featuring such top talent as George Clooney, Charlize Theron, Robert Duvall, Natalie Portman and Canadian Michael Cera.

Seven newly added films will get the red-carpet gala treatment, including "The Men Who Stare at Goats," starring Ewan McGregor as a reporter chasing a tip from an ex-military figure, played by Clooney.

The dark comedy, co-starring Jeff Bridges and directed by Grant Heslov, is Clooney's second at the fest this year, after the previously announced "Up in the Air," lensed by Montreal's Jason Reitman.

Theron and Duvall team up with Viggo Mortensen and Guy Pearce in "The Road," a post-apocalyptic tale of survival adapted from the Pulitzer Prize-winning novel by Cormac McCarthy.

In "Love and Other Impossible Pursuits," having its world premiere in gala form, Portman stars as a law-school graduate reeling from the loss of her newborn daughter. Lisa Kudrow of "Friends" fame co-stars.

Cera portrays a teen trying to lose his virginity and win the heart of a girl, played by Portia Doubleday, in "Youth in Revolt."

Based on the cult-hit novel by C.D. Payne, the feature is directed by Miguel Arteta, best known for directing beloved TV series including "The Office," "Six Feet Under" and "Freaks and Geeks."

Other cast members include Steve Buscemi, Ray Liotta, Justin Long and Jean Smart.

Also having its world premiere gala at the fest will be "Mother and Child," a love story starring Annette Bening, Naomi Watts and Samuel L. Jackson.

Rachel Weisz slips into the role of an astronomer in fourth-century Egypt in "Agora Alejandro Amenabar," also unspooling in gala form.

In the drama "The Joneses," Demi Moore and David Duchovny portray a seemingly perfect couple with a secret.
