Little Thirteen is a 2012 German drama film directed by Christian Klandt.

The film stars Muriel Wimmer as one of three troubled teenagers from different social backgrounds that face various challenges.

[1][2] Thirteen-year-old Sarah (Muriel Wimmer) is no stranger to sex and one-night stands, nor is her sixteen-year-old best friend Charly (Antonia Putiloff).

At the same time Charly has to figure out what she is to do about her pregnancy and her desire to find a father for the unborn child.

To accompany the underage actresses Muriel Wimmer and Antonia Putiloff during the shooting of their nude and sex scenes, the director Christian Klandt and his film team were supported by two sex education specialists from 'pro familia Berlin'.
