She's Lost Control is a 2014 American drama film written and directed by Anja Marquardt in her directorial debut, nominated for two Film Independent Spirit Awards. The film stars Brooke Bloom as Ronah, a sexual surrogate whose professional intimacy with her male clients has begun to take over her personal life. The film premiered at the 64th Berlin International Film Festival on February 9, 2014, where it won the Forum section's top prize, the CICAE International Confederation of Art Cinemas Award, being called a "masterpiece" by the jury. One month later, She's Lost Control had its North American premiere at the SXSW Film Festival, followed by a New York premiere at the New Directors/New Films Festival at Film Society of Lincoln Center and MoMa, where it was described as a "stylish, deeply unnerving, and profound film on an intangible modern issue."

The film was released theatrically in the United States by Monument Releasing on March 20, 2015, in Germany May 14, 2015, and in France July 23, 2015. The title is a reference to the Joy Division song.
