Franz Müller, born on October 20, 1965, in Mosbach/Odenwald, studied Prehistory and Early History and, from 1990 to 1995, studied Fine Arts with Gerhard Richter and Cybernetics with Oswald Wiener in Düsseldorf. From 1999, he pursued postgraduate studies at the Kunsthochschule für Medien Köln under Michael Lentz and Wolfgang Becker. He also collaborated with the Cologne Film Club 813 and wrote for various film magazines. To this day, Franz Müller remains one of the editors of the film magazine Revolver. 

After his first short film "Zwischenwelten" (1997), Müller directed "Madonna ist Löwe" (1998), "Six Degrees of Separation" (1998), "Kaffee x Café" (1999), "Monte Carlo" (2000), and the episode "Vater und Sohn" for the omnibus film "Freitagnacht" (2001). He completed his studies at the Kunsthochschule für Medien with his first feature film, the satirical "Science Fiction" (later titled "Kein Science Fiction"), for which he received the Babelsberger Media Award's promotion prize for best graduation film. 

In 2010, his second feature film "Die Liebe der Kinder" ("Love of the Children" / "Wallace Line") premiered in cinemas. The story about a seemingly perfectly blended family that begins to unravel was awarded prizes at the film festivals in Schwerin and Biberach. 

Collaborating with writer Rainer Knepperges, Müller directed an episode of the German-Moroccan co-production "24h Marrakech" (2010), followed by the short films "Leichtmatrosen" (2010, co-written by Rainer Knepperges) and "Leichtmatrosen II" (2012, co-directed and co-written with Rainer Knepperges). 

Müller's next feature film, "Worst Case Scenario", premiered at the Munich Film Festival in 2014. The film tells the story of an ex-couple whose attempt to make a comedy about the football European Championship in Poland threatens to spiral into chaos. The following year, "Happy Hour", a comedy about three old school friends whose joint trip to Ireland doesn't go as planned, also premiered at the Munich Film Festival. It was awarded the Förderpreis Neues Deutsches Kino in the "Production" category. "Happy Hour" was released in German cinemas in the spring of 2016.

In the following years, Müller completed the half-hour documentary "2STONED - A Trip to the Sky" (2018) and the half-hour fiction film "Einfach teuflisch" (2018). As a producer, he helped bring Sabine Derflinger's documentary "Alice Schwarzer" (AT/DE, 2022) to life. 

Parallel to these projects, Müller began working in 2018 on his next feature film, "Die Tagebücher von Adam und Eva" ("The Diaries of Adam and Eve"), an eccentric tale of Paradise. The film premiered at the Munich Film Festival in the summer of 2023, with its theatrical release scheduled for January 2025. Even before this, in the fall of 2023, Müller finished shooting his next film, "Das Glück der Tüchtigen", a late sequel to "Die Liebe der Kinder". The release date for this film is still pending.
