Blow Up is a French online film magazine in the form of a web series created and directed by Luc Lagier and produced by Jean-Stéphane Michaux.

[2] In most episodes, someone, usually the series's director Luc Lagier, provides voice-over commentary in a deadpan manner.

[3] Episodes come in the following formats: In late 2010, Blow Up was conceptualized by self-described cinephile Luc Lagier of the Franco-German television network Arte when Joël Ronez of Arte's web division suggested that he create a series similar to a blog or online magazine.

[2] Arte, which had no video series about film at the time and wanted to create one, granted full creative freedom to Lagier[5] and his producer Jean-Stéphane Michaux.

[5] Lagier is uninterested in using the internet for this purpose, because he wants Blow Up to feature scenes that have not already been widely circulated online.
