After studying at the ESSEC and the ENS Louis Lumière, Julien Lahmi started directing several documentaries such as Vietnam Paradiso, released in 2013 and selected in many film festivals. With the short film Le Film de Sa Vie (2007) the early stages of his recylcing cinema appear. From old family videos and home movies, he builds narrative and sensorial films. People who really existed on those original images became characters that Julien Lahmi makes speak thanks to acting and voices.

Next to his cineast activities, Julien Lahmi is also an acting teacher and manages workshops about recylcing cinema (with the projet Back to the roots) and the Mashup Film Festival.
