All of the above is related to my present employer (IFP New Energy). Parts of my other life-time activities are more akin to its homonym IFP.org (Independent Feature Project). Isn't it funny? And now for something completely different: a section on short films information (in french). Collaborative outcomes with Oslo Films (script writing).

And now for something completely different: La vertu d'un la, light blog about numbers and letters

Ce qui précède a trait à mon employeur actuel (IFP Energies nouvelles). Une autre part de mes activités a plus à voir avec l'organisme homonyme appelé IFP.org (Independent Feature Project). Étonnant, non ? Une première bribe : une section portant sur l'actualité du court-métrage. Collabore à Oslo Films (écriture de scénarios).
