Don't be fooled by the parkas—things in Park City, Utah, got muy caliente over the weekend.

For the second year in a row, a primarily Spanish-language film centering on the life of immigrants nabbed the top prize at the Sundance Film Festival.

Following on the heels of last year's dominating winner, Quinceañera, Padre Nuestro (Our Father), a thriller directed by Christopher Zalla, took home the indie film festival's top honor of 2007, nabbing the Grand Jury Prize for a dramatic picture. The flick chronicles a young, illegal Mexican immigrant who hops a truck to New York City to seek out the father he barely knows.

Grace Is Gone won the coveted Audience Award, which bodes well for the John Cusack weepie. Last year the trophy went to current awards-show favorite Little Miss Sunshine.

In Grace, Cusack plays a father who decides to break it to his daughters at an amusement park that their soldier mother was killed in the Iraq war. The film also scored the Waldo Salt Screenwriting Award for writer-director James C. Strouse.

The film was a winner even before the awards ceremony Sunday night, however. The drama was one of the first high-profile buys of the festival, with the Weinstein Company acquiring Grace for $4 million.

Meanwhile, the Grand Prize Jury for a documentary also lauded a Latino production.

Manda Bala (Send a Bullet) received the top prize for chronicling three wealthy but corrupt personalities in the often violent and poverty-stricken nation of Brazil. The film also took home the jury's cinematography award.

The documentary Audience Award went to Hear and Now, a film by Irene Taylor Brodsky, following a decision by her deaf parents to undergo cochlear implant surgery after 65 years of living in silence.

The festival's 26th go-round also honored its share of international fare: Denmark's Enemies of Happiness, a documentary about a young woman elected to Afghanistan's parliament in 2005 during the country's first ever democratic vote, won the World Cinema Jury Prize, while Israel's Sweet Mud, about a mentally ill woman and her son on a kibbutz in the 1970s, took home the same award on the dramatic side.

Ireland's modern-day musical Once, following a busker on the streets of Dublin, nabbed the World Cinema Audience Award, while the British astronaut documentary In the Shadow of the Moon took home the complementary dramatic nod.

Special honors went out to a range of films in competition, with the Documentary Jury's Special Jury Prize awarded to Charles Ferguson's No End in Sight, an account of the U.S.'s numerous failures in the Iraq war.

The Alfred P. Sloan Prize, which awards $20,000 to films relating to science or technology and whose jury was headed up by director Darren Aronofsky, went to Chen Shi-Zheng's Dark Matter.

While some of the festival's most star-studded flicks failed to win kudos, that didn't stop studios from snatching them up with hopes for next year's awards season. (Aside from Little Miss Sunshine, Half Nelson is another awards-show contender this season that was snapped up at last year's festival.)

Wet Hot American Summer director David Wain's latest effort, The Ten, a comedy spoofing the unlikely subject of the Ten Commandments, was picked up in a last-minute deal over the weekend, with ThinkFilm nabbing the rights for $4.5 million and aiming for a summer release.

IFC and Netflix teamed up once again this year to buy the Greek tragedy-inspired documentary Protagonist for a low-six figure sum.

Several high-profile flicks still have not been bought. Steve Buscemi's Sienna Miller-starring drama, Interview, had no takers at the fest's close, nor did big winners Padre Nuestro, Once or Manda Bala, though they are expected to go quickly in the wake of their respective victories.

Waitress, starring Keri Russell and written by Adrienne Shelley, who was murdered on the eve of the festival, was picked up jointly by the Weinstein Company and Fox Searchlight for more than $4 million, jointly so as to avoid an escalating bidding war, as was The Same Moon, another immigrant drama that the two companies bought for $5 million.

Last week, King of California, starring Michael Douglas, went for $3 million, while Dedication, starring Mandy Moore and Billy Crudup, sold for roughly the same amount.

The biggest buy of the fest, however, was reportedly Son of Rambow, a quirky British coming-of-age film, snapped up for $7.75 million.

Though that's not to say all movies screened at Sundance have been blessed with a happy ending.

The controversy-courting Hounddog, which features Dakota Fanning's character getting raped, has yet to find a distributor.
