Jan Fantl is a son of director Thomas Fantl. After Thomas Fantl was barred from working in 1957, he moved with his family to Germany, where Jan Fantl was raised.
Jan Fantl passed his Abitur in Frankfurt am Main in 1975 and started working as a unit production manager at Bavaria Film; he became first assistant director and assistant editor two years later. During this period, Fantl mainly worked with Hajo Gies, producing films and episodes of Tatort. He finished this period as a Second Unit Director on Schimanski's first theatrical debut, Zahn um Zahn. Meanwhile, he was hired to assist Wolfgang Petersen (Planübung), Franz Peter Wirth (Wallenstein), and Peter Adam (Tatort).
From 1984 to 1987, he worked as a writer and director for the German Sesame Street. From 1981 until 1988, he worked as producer, writer and director for advertising and corporate promotionals. Beginning 1991, he worked as a line producer on the Icelandic movie Tár úr steini, which was considered for the Academy Award for Best Foreign Language Film in 1996. For the TV pilot Der Clown, he was in charge as Executive Producer in 1996.
Since 1997, Fantl has worked as a producer and entrepreneur who specializes in realizing Hollywood movies in Europe, e.g. eXtreme Ops, and the musical-drama Beyond the Sea, starring Kevin Spacey, Kate Bosworth, John Goodman and Bob Hoskins. The story mainly takes place in the United States, but the movie was shot almost entirely in Germany at Filmstudios Babelsberg and in Berlin. Fantl also co-produced The Musketeer and A Sound of Thunder.
Since 2008, he lived and worked from Prague and since 2011 in London.
