“The L Word” star Jennifer Beals is set to topline and produce “The Lord of Vinyl,” an indie jazz pic that will mark the directorial debut of Dennis Bartok, who wrote the script and will also produce with Patrick Cunningham (“Martha Marcy May Marlene”).Story follows the bittersweet life and comic despair of a lonely fortysomething Angeleno who’s obsessed with jazz, and finds himself exploring the possibility of new love with an unhappily married post office worker (Beals) . A major plot point involves the possibility of a single surviving recording by the enigmatic “godfather of jazz,” New Orleans musician Buddy Bolden, who inspired Louis Armstrong before he died in a Louisiana mental hospital in 1931. Bartok previously wrote and produced Lionsgate’s anthology horror film “Trapped Ashes,” which screened at the Cannes and Toronto film fests in 2006. Cunningham is coming off an Independent Spirit Award nomination for producing Fox Searchlight’s “Martha Marcy May Marlene” with Chris Maybach and Borderline Films. He recently produced Sean Baker’s “Starlet,” which premieres at SXSW this month. Beals, who recently starred on Fox’s “The Chicago Code,” is best known for starring in “Flashdance,” as well as the Denzel Washington pics “The Book of Eli” and “Devil in a Blue Dress.” She’s repped by APA, Greenlight Management and Production and Loeb & Loeb.
