    Brad and Jen Reunite?

    Brad Pitt was in Toronto for the premiere of 'Burn After Reading.' Jennifer Aniston was there for the premiere of 'Management.' And somewhere in the middle, the two exes met for dinner -- supposedly. With the two of them in the same city, the rumors were inevitable: They range from "Brad and Jen had a quiet drink" to "Brad and Jen had a business dinner" to "Jen was so excited for dinner and then Brad stood her up!" What really happened? We may never know. That's why we love the tabloids.

    Keira Could Get an Oscar Nom, Still Needs to Eat a Cheeseburger

    Keira Knightley is at the top of her period-piece-loving game in 'The Duchess,' playing the eponymous Duchess of Devonshire, a woman who fights for feminine independence and true love but is trapped in a marriage that threatens to strip her of both. While the film could earn her and co-star Ralph Fiennes (he's brilliantly loathsome as her philandering husband) Oscar nods, Keira's emaciated appearance in Toronto had many hoping the film gets her a free lifetime supply of Burger King instead.

    Zac Efron Brings the Drama in 'Welles'

    'Me and Orson Welles' was one of the most pleasant surprises of the festival, thanks in large part to Zac Efron's lead performance as a young actor who hustles his way into a 1937 Welles stage production of 'Caesar.' Efron proves he can bring more than just song and dance (but don't you worry 'HSM' maniacs, he still sings, and his hair is just as impressive). Also of note is British newcomer Christian McKay, who gives a tour de force performance as the larger-than-life Welles.

    'Burn After Reading' Sets Toronto on Fire

    Though the Coen Brothers' 'No Country for Old Men' follow-up divided critics into those who saw it as a misanthropic indictment of American intelligence and those who simply thought it was funny as hell (we count ourselves among the latter), there's no denying that 'Burn After Reading' was the big event movie of the festival. Thousands upon thousands of screaming fans lined the streets at the premiere -- some climbing ladders and walls -- just to get a glimpse of Brad Pitt's red carpet stroll. We bet the Toronto streets are still reverberating with echoes of "Braaaaaaaad!"

    Kevin Smith Is a Sex Machine

    'Clerks' auteur Kevin Smith takes his renowned raunchiness to new heights (like the stratosphere) with 'Zack and Miri Make a Porno,' thanks to tons of profanity, frank sex talk (mostly about filthy orifices) and some niftily staged soft-core fornicating that could teach Skinemax a thing or two. As platonic roommates who agree to make an amateur skin flick to pay their overdue bills, Seth Rogen and Elizabeth Banks are gushing volcanoes of chemistry, once and for all giving audiences a schlubby guy-ridiculously hot girl romance that's 100 percent believable.

    Rourke Could Body Slam His Way to Oscars

    The story of a has-been who was huge in the '80s and now struggles to collect a paycheck? It's not a Mickey Rourke biopic, but Darren Aronofsky's excellent 'The Wrestler,' and it's the sort of comeback vehicle that could resurrect a career (think Travolta in 'Pulp Fiction'). The buzz for the troubled actor's powerhouse performance has been massive, with Evan Rachel Wood and Marisa Tomei also turning in stellar work in supporting parts.

    'Nick and Norah' Provides 'Infinite' Fun

    Think the hopeful romance of 'Before Sunset' and the raunchy humor of 'Superbad' and you've got the picture. Chronicling one crazy night in the life of mismatched teens Nick (Michael Cera) and Norah (Kat Dennings) on a quest to find a secret show by their elusive favorite band, 'Nick and Norah's Infinite Playlist' should score big with the 25-and-under crowd. Not to be upstaged by the movie, the young stars didn't hold back at the premiere after party, with the cast (led by the interestingly dressed Aaron Yoo) dancing the night away and mugging for photogs.

    Hathaway Gets Oscar Buzz, Ex Gets Jail Time

    Toronto treated Anne Hathaway well, with the debut of 'Rachel Getting Married' earning her career-best reviews. But just as she was scoring Oscar talk for her raw, captivating performance as recovering drug addict/emotional train wreck Kym in Jonathan Demme's family drama, Anne's ex-boyfriend was experiencing his own personal drama. Raffaello Follieri was sentenced to more than four years in prison for wire fraud, money laundering and conspiracy. That has to sting.

    Van Damme! That Guy Can Act

    Remember Jean-Claude Van Damme, aka the Muscles From Brussels and martial arts star of such '80s-'90s hits as 'Bloodsport' and 'Universal Soldier'? Well, he's back -- and it turns out he can act, a talent he showcases almost as much as his 47-year-old (but still impressive) biceps in the delightfully meta 'JCVD.' Playing himself, an aging star/ex-drug addict now relegated to competing with Steven Seagal for direct-to-DVD roles, the Muscles shows sides of himself never before seen. You'll laugh, you'll cheer and your heart muscle will ache for the big lug from Belgium.
