Bavaria adds to ‘Prime Numbers’

Based on bestseller, stars Isabella Rossellini

BERLIN — Bavaria Pictures has inked a co-production deal with Mario Gianani’s Offside to film Italo bestselling novel “The Solitude of Prime Numbers” by Paolo Giordano.

Pic is being helmed by Saverio Costanzo and features Isabella Rossellini and Italian thesp Alba Rohrwacher.

Further partners in pic, planned for release in late 2010, are Les Films des Tournelles from France as well as ZDF Enterprises and Ostlicht Filmproduktion in Germany. Producers are Gianani, Philipp Kreuzer and Anne Dominique Toussant. Pic will receive funding from the Mitteldeutsche Medienfoerderung (MDM), Film Commission Torino Piemonte and Eurimages.

Pic began filming in Rome, and from October to early February will move to Turin and Piemont — after that in the eastern German state of Thuringia, where postproduction and animation work will be done.

Costanzo burst on the fest circuit with his debut “Private,” which took the 2004 Locarno Golden Leopard, followed by “In Memory of Myself,” which went to Berlin.

Giordano’s novel, which turns on trauma, love and math, won Italy’s top literary prize, the Premio Strega. It has since been published in 25 languages. Doubleday published “Solitude” in the U.S. in June.

Rohrwacher most recently co-starred with Tilda Swinton in Luca Guadagnino’s “I Am Love.” In “Solitude,” she will play a young woman dealing with an emotional, as well as physical, scar dating back to her childhood.

Gianani’s Offside, a recently launched Rome shingle, was behind Marco Bellocchio’s “Vincere.” Medusa is financing “Solitude” and will release the pic in Italy.
