The Orchard has acquired North American rights to Song of Back and Neck, the feature film debut of The Office writer-producer-actor Paul Lieberstein that bowed this year at Tribeca. Rosemarie DeWitt, Brian D’Arcy James, Robert Pine, Clark Duke and Paul Feig co-star in the pic, which will get a 2018 release. Lieberman plays Fred, resigned to a lifetime of back pain who has tried every possible remedy — except for having an affair with a client (DeWitt) at the start of her complicated divorce, or trying her acupuncturist whose 200 needles in Fred’s back reveal a bizarre talent, or beginning to wonder if his problems are more psychological than physical. Lieberstein produces with Kim Leadford and StarStream Media’s Jennifer Prediger, and Fernando Loureiro, Roberto Vasconcellos, Candice Abela-Mikati, Allen Babakhanloo and Lauren Russell executive produce. The deal was made by The Orchard’s Danielle Digiacomo and CAA Media Finance on behalf of the filmmakers.
