Sebastian Koch ("The Lives of Others") and Julia Jentsch have signed on to star in Constantin Film's adaptation of Theodor Fontane's classic 19th century novel "Effi Briest."
Jentsch ("Sophie Scholl -- The Final Days") will take the title role of a young woman caught between an arranged marriage with the much older Baron von Instetten (Koch) and an ill-advised love affair.
Juliane Koehler ("Downfall") has also signed on to the project, playing Effi's mother Luise von Briest.
