During the first month or so of the year, two distinct groups of movie-lovers emerge. There are those privileged few who haul their frostbitten carcasses through no-degree weather to wait in line for two or perhaps three hours, just to see a movie of unknown quality. Then there are those of us deeply envious of the people who get the chance to do that.

For those not freezing their buns off in Park City, impressions of the films in competition at Sundance may extend to breathless reaction-tweets, and little else. But many production companies wisely capitalize on the spike in attention that accompanies Sundance, and roll out trailers or short clips from their offerings. Here are two of the more recent video previews that have surfaced online.

Retro-futurism is a weird but reliably fun phenomenon in fiction, defined as an off-base vision of the future as imagined by the past. This can happen naturally with the passage of time (the authoritarian 1994 of 1980’s disco fantasia The Apple didn’t exactly pan out), or it can be a deliberate move used to indulge in far-out stylization (Sky Captain And The World Of Tomorrow nicks the heady visions of floating cities that dominated science fiction in the 1930s) and ironic humor. (Richard Ayoade’s ingenious TV series Garth Marenghi’s Darkplace shows clips from an allegedly lost science-fiction masterpiece from the 1980s.) The Midnight sidebar breakout Turbo Kid taps into that last tradition, envisioning a dystopian 1997 ruled by bloody practical effects. Imagine if that Road Warrior remake your 11-year-old self made with your friends using your dad’s camcorder actually turned out well, and you’re getting close.

Jared Hess’ Napoleon Dynamite is the Sundance success story that launched a million twee soundtracks. “Offbeat comedy with a $400,000 budget spins a $46 million box-office return” is the sort of narrative that gets studio executives out of bed in the morning, and after the well-intentioned misfire Gentleman Broncos, Hess and his wife and creative partner Jerusha are giving it another shot. Don Verdean stars Sam Rockwell in the title role, as an archaeologist tasked by a local megachurch with digging up sacred relics. When his search turns up dry, the resulting cover-up quickly gets out of hand.
