Single by Contract (German: Groupies bleiben nicht zum Frühstück [Groupies don't stay for breakfast]) is a 2010 German comedy film directed by Marc Rothemund.
The feature film is based on a screenplay by Kristina Magdalena Henn and Lea Schmidbauer and tells the story of the Berlin schoolgirl Lila, played by Anna Fischer, who falls in love with the aspiring musician Chriz, portrayed by Kostja Ullmann, after returning from an exchange year in the United States — unaware that he is the lead singer of the commercially successful rock band Berlin Mitte.
The project was produced by SamFilm in Munich. Filming took place from August to October 2009 in and around Berlin. In addition to Fischer and Ullmann, the cast included Inka Friedrich, Amber Bongard, Nina Gummich, Roman Knižka, and Ben Braun.
Critics generally reviewed Single By Contract positively and compared the production to the English-language romantic comedy Notting Hill (1999). With more than 600,000 cinema-goers in Germany, the film became the eleventh most successful German production of the 2010 cinema year.
