Blueprint (2003)

Run Lola Run (1999) star Franka Potente demonstrates her acting chops by playing two roles in the futuristic German drama Blueprint (2003). Potente stars as Siri Sellin, a talented pianist who bears more than a passing resemblance to her mother, Iris (also played by Potente). It turns out that there’s a good reason for that--more than merely progeny, Siri is actually a cloned version of Iris (note the front-to-back spelling). Understandably creeped out by the revelation, the younger Sellin flees home and into the arms of Hilmir Snaer Gudnason, who’s all too happy to offer some sexual healing.
