BERLIN — Local filmmakers Oskar Roehler and Peter Ott are gearing up for a couple of ambitious projects, with the former prepping a multi- generational tale spanning four decades, and the latter set to shoot an Iraq-set thriller about a doctor kidnapped by militants.

Roehler, director of “Jew Suss: Rise and Fall” and “Elementary Particles,” will next shoot “Die Quellen des Lebens” (The Sources of Life), the story of a family over a 40-year period and three generations.

Produced by Berlin-based X Filme, the pic’s cast includes Juergen Vogel (“The Wave”), Martina Gedeck (“The Baader Meinhof Complex”), Nora Tschirner (“Rabbit Without Ears”) and Matthias Schweighoefer (“Friendship”).

Regional film funder Filmstiftung North Rhine-Westphalia is backing the production with Euros 1.6 million ($2.2 million).

In Ott’s “Die Monotheistische Zelle” (The Monotheistic Cell), Sophie Rois, who appeared in Tom Tykwer’s romantic triangle drama “Three,” stars as a doctor who begins to question her entire existence after being kidnapped by a Shi’ite group in Iraq.

Produced by Colonia Media, the project picked up $685,122 from Filmstiftung NRW.
