Vintage pornography is also having a moment at repertory movie theaters and mainstream museums. An exhibition now at the Museum of Sex in Manhattan is devoted to the actress Linda Lovelace, who starred in the 1972 film “Deep Throat.” Closing Sunday, at the Museum of Contemporary Art in Los Angeles, is the first American museum show to feature the homoerotic works of the illustrator Touko Laaksonen, a.k.a. Tom of Finland (1920-91), and the photographer Bob Mizer (1922-92). Last year, the Yerba Buena Center for the Arts in San Francisco hosted “X: The History of a Film Rating,” a film series that included showings of “Last Tango in Paris” and “Midnight Cowboy.”

In New York, several adventurous film programmers — many too young to remember the region’s “adult film” past — are teaming with Vinegar Syndrome to present X-rated releases on the big screen. Nitehawk Cinema in Brooklyn is partnering with the company on a yearlong series, Nitehawk Naughties, devoted to restorations of films from the ’70s, including “The Opening of Misty Beethoven,” which will be shown on Jan. 31. The CineKink festival, which focuses on sex-related cinema, showed “Misty Beethoven” last year, and hopes to feature one of Vinegar Syndrome’s restored releases at its next festival in February, said Lisa Vandever, CineKink’s director.

In March, Anthology Film Archives, the Manhattan center that focuses on experimental and avant-garde projects, will continue its “In the Flesh” series of hard-core X-rated films from Vinegar Syndrome and Distribpix, a distributor of X-rated movies that through the 1980s actually produced films. All of the titles will be shown on 35 millimeter, as they were originally. Together, they reflect the era of what Anthology is calling “porn chic,” which started in the early ’70s when hard-core sex met high production values.

“In the ’70s, adult films were made on 16 or 35 millimeter, and were projected to an audience,” said Casey Scott, who programs this Anthology series. “They were reviewed by Variety and The New York Times.” That era, when films were made under threat of legal action, ended in the early ’80s, when home video brought pornography into living rooms.
