Leonine Studios and Mediawan have boarded upcoming English-language horror “The Twin” for German-speaking and French-speaking territories respectively in a deal inked by Film Constellation.

Don Films has unveiled a first image of the film by Finnish director Taneli Mustonen (“Lake Bodom”), which recently wrapped principal photography in Estonia and Finland. First footage will be shown to buyers at the Cannes Film Market. “The Twin” has also been selected to take part in Frontières Platform, the genre-focused event run by Fantasia and Cannes Film Market.

Teresa Palmer (“Lights Out,” “Warm Bodies,” “A Discovery of Witches”) stars in the lead role of a young mother plagued by the violent death of one of her twins. The film also stars Steven Cree (“A Discovery of Witches,” “Terminator: Dark Fate”) and Barbara Marten (“The Turning”). As the family sets out to rebuild their lives in the quiet Scandinavian countryside, they soon come to realize that some secrets are so evil they need to be buried twice.

“The Twin” had previously sold in the Benelux (Dutch Filmworks); CIS (Nashe Kino); MENA (Falcon Films); Taiwan (Deepjoy Picture Corporation); Indonesia (PT Prima); Vietnam, Malaysia, Cambodia, Brunei (Suraya Filem); North America, U.K./Ireland, ANZ (AMC’s Shudder); and Scandinavia (Nordisk Film).

“The Twin” is written by Taneli Mustonen and Aleksi Hyvärinen. It is produced by Don Films’ Aleksi Hyvärinen (“Arrhythmia,” “Lake Bodom”). Executive producers are Joris van Wijk, Shudder’s Emily Gotto, Film Constellation’s Fabien Westerhoff, and Post Control Helsinki’s Toni Valla. The film is backed by Shudder, Playtime, Nordisk Film, the Finnish Film Foundation, Estonian Film Institute and the Finnish television channel MTV3.

Palmer is represented by ICM Partners, Management 360 and Sloane, Offer, Weber, & Dern, and Shanahan in Australia.
