As the night grew darker, a cold wind whipped across the asphalt expanse of the vintage Rubidoux Drive-In Theatre in Riverside. A howling gust banged open the door to the snack bar, where hot dogs glistened on metal spits and the black-and-white linoleum floor gleamed.
Quentin Tarantino's "Django Unchained" flickered to life on the colossal screen — for an audience of eight cars.
This time of year is always slow at drive-in theaters, which have been struggling with declining attendance for decades. But it's not just cold weather that has made this a winter of discontent. The digital revolution is here, and that could mean lights out for many of the nation's 368 surviving drive-ins.
Hollywood is expected to stop distributing 35-millimeter film prints to all U.S. theaters later this year. The vast majority of indoor theaters — hardtops, in drive-in lingo — have already converted to digital projectors, but 90% of drive-ins have not, according to an industry trade group. Conversion costs of $70,000 or more per screen could be too expensive for many drive-ins.
The Rubidoux plans to convert to digital projection, but its owner says the switch will be a struggle for many others.
"There's been panic, definitely," Frank Huttinger said. "Ma and pop outfits, second- or third-generation places, are hesitant to put up all that money."
The drive-in market today is a shell of what it was in the late 1950s, when teens and big families in big cars found drive-ins a fun alternative to indoor theaters. At their peak, there were more than 4,000 drive-ins, accounting for 25% of the nation's movie screens. Today, that's down to 1.5%.
By the late 1980s, more than three-quarters of American drive-ins had closed as multiplexes proliferated. Urban sprawl and soaring land values led many to be bulldozed to make way for malls and other commercial developments.
The drive-ins that survived have been doing better in the last decade, spurred partly by cost-conscious families who can see double features or first-run movies at half the price of the hardtops, said National Assn. of Theatre Owners spokesman Patrick Corcoran.
For younger audiences, there's the chance to travel back in time.
"My car's pretty roomy, and it's chill to sit there together," said Casey Welch, 19, who was at the Rubidoux Drive-In with girlfriend Jonnie Byrd.
In most of the country, drive-ins close for the winter. Some may not reopen this spring because of the high cost of digital conversion, said John Vincent Jr., the president of the United Drive-In Theatre Owners Assn. He declined to speculate on the number that may close.
None of the eight operating drive-in theaters in Southern California have yet converted to digital.
"It's a tough pill to swallow," Vincent said. He plans to spend $75,000 to convert the drive-in he owns on Cape Cod.
More than a decade ago, Hollywood created a financing plan to help traditional indoor theaters with the digital transition. Each time a cinema shows a digital movie, the studios give them a so-called digital print fee funded by the nearly $1,300 that the studios save on making and shipping a 35-mm print, said Chris McGurk, the chairman and chief executive of Cinedigm, a digital equipment provider for theaters.
But there is no such plan for drive-ins. Cinedigm and NATO officials said they are negotiating with the studios for a virtual print fee for drive-ins, but neither they nor studio officials could give details of the plan or say when it would be introduced.
The Rubidoux is owned by Los Angeles-based DeAnza Land & Leisure Corp. Huttinger, De Anza's chief executive, said converting 21 screens at all six of his company's drive-ins would cost nearly $2 million.
Drive-ins have unique projection needs. The booth typically sits more than a football field away from the screen, so the projector needs a much more powerful bulb to carry the image. Booths with a digital projector also need to be retrofitted with special glass, more vents, stronger air-conditioning and an Internet connection. Projectionists who used to put film onto reels will instead insert a jump-drive into a server the size of a refrigerator.
Jeff Kohlberg, the owner of the Cascade Drive-In in West Chicago, created a Kickstarter online fundraising campaign to help pay for his $100,000 conversion. He raised $1,200. Because getting film this summer seems "wishy-washy at best," he's forging ahead, using extra profits from this year and some money from his landlord.
